In HMAC_Init_ex, NULL key signals reuse, but in single-shot HMAC,
we can allow it to signal an empty key for convenience.

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.

This change required some special treatment, as HMAC is intertwined
with EVP_MD. For now, all local HMAC_CTX variables MUST be
initialised with HMAC_CTX_EMPTY, or whatever happens to be on the
stack will be mistaken for actual pointers to EVP_MD_CTX. This will
change as soon as HMAC_CTX becomes opaque.
Also, since HMAC_CTX_init() can fail now, its return type changes from
void to int, and it will return 0 on failure, 1 on success.

Recent HMAC changes broke ABI compatibility due to a new field in HMAC_CTX.
This backs that change out, and does it a different way.
Thanks to Timo Teras for the concept.

Rather than making include/openssl/foo.h a symlink to
crypto/foo/foo.h, this change moves the file to include/openssl/foo.h
once and for all.
Likewise, move crypto/foo/footest.c to test/footest.c, instead of
symlinking it there.
