Update libjpeg to 9e

Bug 697186: Workaround JPEG lib bug.

in any real world cases, but is more correct.

Squash MSVC build warning.

Couple of compiler warnings in the libjpeg sources

+IJG JPEG LIBRARY:  ALTERNATE USER INTERFACE FOR CJPEG/DJPEG
+
+Copyright (C) 2020, Guido Vollbeding.
+This file is part of the Independent JPEG Group's software.
+For conditions of distribution and use, see the accompanying README file.
+
+
+There is an alternate command-line user interface for the IJG JPEG software.
+It is designed for use under MS-DOS, and may also be useful on other non-Unix
+operating systems.  (For that matter, this code works fine on Unix, but the
+standard command-line syntax is better on Unix because it is pipe-friendly.)
+
+With this user interface, cjpeg and djpeg accept multiple input file names
+on the command line; output file names are generated by substituting
+appropriate extensions.  The user is prompted before any already-existing
+file will be overwritten.
+
+Expansion of wild-card file specifications is useful but is not directly
+provided by this code.  Most DOS C compilers have the ability to do wild-card
+expansion "behind the scenes", and we rely on that feature.  On other systems,
+the shell may do it for you, as is done on Unix.
+
+Also, a DOS-specific routine is provided to determine available memory;
+this makes the -maxmemory switch unnecessary except in unusual cases.
+If you know how to determine available memory on a different system,
+you can easily add the necessary code.  (And please send it along to
+jpeg-info@jpegclub.org so we can include it in future releases!)
+
+
+INSTALLATION
+============
+
+Rename the standard cjpeg.c file to cjpegstd.c, then rename cjpegalt.c to
+cjpeg.c.
+Rename the standard djpeg.c file to djpegstd.c, then rename djpegalt.c to
+djpeg.c.
+Then build the software as described in install.txt, with these exceptions:
+
+* Define PROGRESS_REPORT in jconfig.h if you want the percent-done display.
+* Define NO_OVERWRITE_CHECK if you *don't* want overwrite confirmation.
+* You may ignore the USE_SETMODE and TWO_FILE_COMMANDLINE symbols discussed
+  in install.txt; these files do not use them.
+* As given, djpegalt.c defaults to BMP output (not PPM output as in the
+  standard djpeg.c).  If you want something different, modify DEFAULT_FMT.
+
+You may also need to do something special to enable filename wild-card
+expansion, assuming your compiler has that capability at all.
+
+Modify the standard usage.txt file as described below.  (If you want to use
+the Unix-style manual pages cjpeg.1 and djpeg.1, better fix them too.)
+
+To restore the standard user interface:
+Rename cjpeg.c to cjpegalt.c, then rename cjpegstd.c to cjpeg.c.
+Rename djpeg.c to djpegalt.c, then rename djpegstd.c to djpeg.c.
+Then recompile/rebuild.
+
+
+Here are some specific notes for popular MS-DOS compilers:
+
+Borland C:
+  Add "-DMSDOS" to CFLAGS to enable use of the DOS memory determination code.
+  Link with the standard library file WILDARGS.OBJ to get wild-card expansion.
+
+Microsoft C:
+  Add "-DMSDOS" to CFLAGS to enable use of the DOS memory determination code.
+  Link with the standard library file SETARGV.OBJ to get wild-card expansion.
+  In the versions I've used, you must also add /NOE to the linker switches to
+  avoid a duplicate-symbol error from including SETARGV.
+
+DJGPP (we recommend version 2.0 or later):
+  Add "-DFREE_MEM_ESTIMATE=0" to CFLAGS.  Wild-card expansion is automatic.
+
+
+USAGE
+=====
+
+Most of the standard usage.txt file also applies to the alternate version,
+but replace its "GENERAL USAGE" section with the text below.  Edit the text
+as necessary if you don't support wildcards or overwrite checking.  Be sure
+to fix the djpeg switch descriptions if you are not defaulting to PPM output.
+Also, if you've provided an accurate memory-estimation procedure, you can
+probably eliminate the HINTS related to the -maxmemory switch.
+
+
+GENERAL USAGE
+
+We provide two programs, cjpeg to compress an image file into JPEG format,
+and djpeg to decompress a JPEG file back into a conventional image format.
+
+The basic command line is:
+	cjpeg [switches] list of image files
+or
+	djpeg [switches] list of jpeg files
+
+Each file named is compressed or decompressed.  The input file(s) are not
+modified; the output data is written to files which have the same names
+except for extension.  cjpeg always uses ".jpg" for the output file name's
+extension; djpeg uses one of ".bmp", ".gif", ".ppm", ".rle", or ".tga",
+depending on what output format is selected by the switches.
+
+For example, to convert xxx.bmp to xxx.jpg and yyy.ppm to yyy.jpg, say:
+	cjpeg xxx.bmp yyy.ppm
+
+On most systems you can use standard wildcards to specify the list of input
+files; for example, on DOS "djpeg *.jpg" decompresses all the JPEG files in
+the current directory.
+
+If an intended output file already exists, you'll be asked whether or not to
+overwrite it.  If you say no, the program skips that input file and goes on
+to the next one.
+
+You can intermix switches and file names; for example
+	djpeg -gif file1.jpg -targa file2.jpg
+decompresses file1.jpg into GIF format (file1.gif) and file2.jpg into Targa
+format (file2.tga).  Only switches to the left of a given file name affect
+processing of that file; when there are conflicting switches, the rightmost
+one takes precedence.
+
+You can override the program's choice of output file name by using the
+-outfile switch, as in
+	cjpeg -outfile output.jpg input.ppm
+-outfile only affects the first input file name to its right.
+
+The currently supported image file formats are: PPM (PBMPLUS color format),
+PGM (PBMPLUS grayscale format), BMP, GIF, Targa, and RLE (Utah Raster Toolkit
+format).  (RLE is supported only if the URT library is available, which it
+isn't on most non-Unix systems.)  cjpeg recognizes the input image format
+automatically, with the exception of some Targa-format files.  You have to
+tell djpeg which format to generate.
+
+JPEG files are in the standard JFIF file format.  There are other,
+less widely used JPEG-based file formats, but we don't support them.
+
+All switch names may be abbreviated; for example, -grayscale may be written
+-gray or -gr.  Most of the "basic" switches can be abbreviated to as little as
+one letter.  Upper and lower case are equivalent (-BMP is the same as -bmp).
+British spellings are also accepted (e.g., -greyscale), though for brevity
+these are not mentioned below.

+ * guarantee that more than one character can be pushed back with ungetc.
+ * Looking at additional bytes would require one of these approaches:
+ *     1) assume we can fseek() the input file (fails for piped input);

+ * or  4) don't put back the data, and modify the input_init methods to assume
+ *        they start reading after the start of file (also breaks RLE library).
+ * #1 is attractive for MS-DOS but is untenable on Unix.
+ *
+ * The most portable solution for file types that can't be identified by their
+ * first byte is to make the user tell us what they are.  This is also the
+ * only approach for "raw" file types that contain only arbitrary values.
+ * We presently apply this method for Targa files.  Most of the time Targa
+ * files start with 0x00, so we recognize that case.  Potentially, however,
+ * a Targa file could start with any byte value (byte 0 is the length of the
+ * seldom-used ID field), so we provide a switch to force Targa input mode.

-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking ...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
-
-Installation directories:
-  --prefix=PREFIX         install architecture-independent files in PREFIX

-  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
-                          [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.

-  --with-sysroot[=DIR]    Search for dependent libraries within DIR (or the
-                          compiler's sysroot if not specified).
-
-Some influential environment variables:
-  CC          C compiler command
-  CFLAGS      C compiler flags
-  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
-              nonstandard directory <lib dir>
-  LIBS        libraries to pass to the linker, e.g. -l<library>
-  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
-              you have headers in a nonstandard directory <include dir>
-  CPP         C preprocessor
-  LT_SYS_LIBRARY_PATH
-              User-defined run-time library search path.
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.
-
-Report bugs to the package provider.
