Refactor util/mkdef.pl for clearer separation of functionality
Move the .num updating functionality to util/mknum.pl. Rewrite util/mkdef.pl to create .def / .map / .opt files exclusively, using the separate ordinals reading module. Adapt the build files. Adapt the symbol presence test. Reviewed-by: Tim Hudson <tjh@openssl.org> (Merged from https://github.com/openssl/openssl/pull/7191)

-#
-# generate a .def file
-#
-# It does this by parsing the header files and looking for the
-# prototyped functions: it then prunes the output.
-#
-# Intermediary files are created, call libcrypto.num and libssl.num,
-# The format of these files is:
-#
-# routine-name nnnn vers info
-#
-# The "nnnn" and "vers" fields are the numeric id and version for the symbol
-# respectively. The "info" part is actually a colon-separated string of fields
-# with the following meaning:
-#
-# existence:platform:kind:algorithms
-#
-# - "existence" can be "EXIST" or "NOEXIST" depending on if the symbol is
-# found somewhere in the source,
-# - "platforms" is empty if it exists on all platforms, otherwise it contains
-# comma-separated list of the platform, just as they are if the symbol exists
-# for those platforms, or prepended with a "!" if not. This helps resolve
-# symbol name variants for platforms where the names are too long for the
-# compiler or linker, or if the systems is case insensitive and there is a
-# clash, or the symbol is implemented differently (see
-# EXPORT_VAR_AS_FUNCTION). This script assumes renaming of symbols is found
-# in the file crypto/symhacks.h.
-# The semantics for the platforms is that every item is checked against the
-# environment. For the negative items ("!FOO"), if any of them is false
-# (i.e. "FOO" is true) in the environment, the corresponding symbol can't be
-# used. For the positive items, if all of them are false in the environment,
-# the corresponding symbol can't be used. Any combination of positive and
-# negative items are possible, and of course leave room for some redundancy.
-# - "kind" is "FUNCTION" or "VARIABLE". The meaning of that is obvious.
-# - "algorithms" is a comma-separated list of algorithm names. This helps
-# exclude symbols that are part of an algorithm that some user wants to
-# exclude.
-#
+# Generate a linker version script suitable for the given platform
+# from a given ordinals file.
