Apart from public and internal header files, there is a third type called
local header files, which are located next to source files in the source
directory. Currently, they have different suffixes like

  '*_lcl.h', '*_local.h', or '*_int.h'

This commit changes the different suffixes to '*_local.h' uniformly.

The goal is to minimize maintenance burden by eliminating somewhat
obscure platform-specific tweaks that are not viewed as critical for
contemporary applications. This affects Camellia and digest
implementations that rely on md32_common.h, MD4, MD5, SHA1, SHA256.
SHA256 is the only one that can be viewed as critical, but given
the assembly coverage, the omission is considered appropriate.

This was done by the following
        find . -name '*.[ch]' | /tmp/pl
where /tmp/pl is the following three-line script:
        print unless $. == 1 && m@/\* .*\.[ch] \*/@;
        close ARGV if eof; # Close file to reset $.

And then some hand-editing of other files.

Some URLs in the source code ended up getting mangled by indent. This fixes
it. Based on a patch supplied by Arnaud Lacombe <al@aerilon.ca>

Since we don't use the eay style any more, there's no point tryint to
tell emacs to use it.

Exported headers shouldn't be included as "foo.h" by code from the same
module, it should only do so for module-internal headers. This is
because the symlinking of exported headers (from include/openssl/foo.h
to crypto/foo/foo.h) is being removed, and the exported headers are
being moved to the include/openssl/ directory instead.

/*
 * This release balances code size and performance. In particular key
 * schedule setup is fully unrolled, because doing so *significantly*
 * reduces amount of instructions per setup round and code increase is
 * justifiable. In block functions on the other hand only inner loops
 * are unrolled, as full unroll gives only nominal performance boost,
 * while code size grows 4 or 7 times. Also, unlike previous versions
 * this one "encourages" compiler to keep intermediate variables in
 * registers, which should give better "all round" results, in other
 * words reasonable performance even with not so modern compilers.
