The OID for {1 3 6 1 5 5 8 1 2} HMAC-SHA1 (NID_hmac_sha1) is explicitly
referenced by RFC 2510, RFC 3370, and RFC 4210. This is essential for the
common implementations of CMP (Certificate Managing Protocol, RFC4210).
HMAC-MD5's OID {1 3 6 1 5 5 8 1 1} (NID_hmac_md5) is in the same branch and
it seems to generally exist (-> Internet search), but it is unclear where it is
actually defined as it appears not to be referenced by RFCs and practically
rather unused.
Those OIDs are both duplicates to OIDs from an RSA OID branch, which are already
included in builtin_pbe[]:
HMAC-SHA1 also has another OID defined in PKCS#5/RFC2898 (NID_hmacWithSHA1).
It is also unclear where the other OID for HMAC-MD5 (NID_hmacWithMD5) from the
RSA branch is officially specified, as only HMAC-SHA1 from PKCS#5 was found to be
defined. Anyway, HMAC-MD5 likely only plays a neglectable role in the future.

Bounds checking strpy, strcat and sprintf.
These are the remaining easy ones to cover a recently removed commit.
Some are trivial, some have been modified and a couple left as they are because the reverted change didn't bounds check properly.

[extended tests]
Original text:
Use BUF_strlcpy() instead of strcpy().
Use BUF_strlcat() instead of strcat().
Use BIO_snprintf() instead of sprintf().
In some cases, keep better track of buffer lengths.

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.

For a local variable:
TYPE *p;
Allocations like this are "risky":
p = OPENSSL_malloc(sizeof(TYPE));
if the type of p changes, and the malloc call isn't updated, you
could get memory corruption. Instead do this:
p = OPENSSL_malloc(sizeof(*p));
Also fixed a few memset() calls that I noticed while doing this.

des_old.h redefines crypt:
#define crypt(b,s)\
DES_crypt((b),(s))
This scheme leads to failure, if header files with the OS's true definition
of crypt() are processed _after_ des_old.h was processed. This is e.g. the
case on HP-UX with unistd.h.
As evp.h now again includes des.h (which includes des_old.h), this problem
only came up after this modification.
Solution: move header files (indirectly) including e_os.h before the header
files (indirectly) including evp.h.

This is mostly a work around for the old VC++ problem
that it treats func() as func(void).
Various prototypes had been added to 'compare' function
pointers that triggered this. This could be fixed by removing
the prototype, adding function pointer casts to every call or
changing the passed function to use the expected arguments.
I mostly did the latter.
The mkdef.pl script was modified to remove the typesafe
functions which no longer exist.
Oh and some functions called OPENSSL_freeLibrary() were
changed back to FreeLibrary(), wonder how that happened :-)

like Malloc, Realloc and especially Free conflict with already existing names
on some operating systems or other packages. That is reason enough to change
the names of the OpenSSL memory allocation macros to something that has a
better chance of being unique, like prepending them with OPENSSL_.
