The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.
In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.
This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.
Fix hash_copy() tests by using correct size for sha3 context
sync config.w32 with with new sha3 files
Move dependency on KeccakHash.h to hash_sha3.c so we do not rely on it to install php_hash_sha3.h
Allocate memory for KeccacInstance in hash_sha3.c so header files do not need to know about implementation details while keeping API backward compatible to original sha3 implementation
Fix memory leak because hash_copy is called after init which already allocates the hashinstance
