Refactor util/mknum.pl for clearer separation of functionality

Rewrite util/mknum.pl to become cleaner, and to use the separate
generic C header parsing module, as well as the separate ordinals
manipulation module.
Adapt the build files.

-# 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.
