Source reorganization. In short:

  * Added directories and moved related files into them:
      - src for the MPFR source files (to build the library).
      - doc for documentation files (except INSTALL, README...).
      - tools for various tools (scripts) and mbench.
      - tune for tuneup-related source files.
      - other for other source files (not distributed in tarballs).
    Existing directories:
      - tests for the source files of the test suite (make check).
      - examples for examples.
      - m4 for m4 files.
  * Renamed configure.in to configure.ac.
  * Added/updated Makefile.am files where needed.
  * Updated acinclude.m4 and configure.ac (AC_CONFIG_FILES line).
  * Updated the documentation (INSTALL, README, doc/README.dev and
    doc/mpfr.texi).
  * Updated NEWS and TODO.
  * Updated the scripts now in tools.

The following script was used:

#!/usr/bin/env zsh
svn mkdir doc other src tools tune
svn mv ${${(M)$(sed -n '/libmpfr_la_SOURCES/,/[^\]$/p' \
         Makefile.am):#*.[ch]}:#get_patches.c} mparam_h.in \
       round_raw_generic.c jyn_asympt.c src
svn mv mbench check_inits_clears coverage get_patches.sh mpfrlint \
  nightly-test update-patchv update-version tools
svn mv bidimensional_sample.c speed.c tuneup.c tune
svn mv *.{c,h} other
svn mv FAQ.html README.dev algorithm* faq.xsl fdl.texi mpfr.texi \
  update-faq doc
svn mv configure.in configure.ac
svn cp Makefile.am src/Makefile.am
svn rm replace_all
[Modifying some files, see above]
svn add doc/Makefile.am
svn add tune/Makefile.am
