Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Fix an 11 year old mistake: Let the hash functions take a void* instead
of unsigned char* argument.

Rename local variables to not mask global names of same name. This
fixes lots of lint(1) warnings.

add __FBSDID()s to libmd

Add a new entrypoint to the hashes in libmd:
char *
FooFileChunk(const char *filename, char *buf, off_t offset, off_t length)
Which only hashes part of a file.
Implement FooFile() in terms of this function.

Imported libmd. This library contains MD2, MD4 and MD5.
These three boggers pop up all over the place all of the time, so I
decided we needed a library with them. In general they are used for
security checks, so if you use them you want to link them static.
