We extracted the SHA-256 source files, eliminated unneeded dependencies,
deleted or commented out unused code, and tweaked them for Chrome's source
tree.  sha512.c is renamed sha512.cc so that it can include Chrome's C++
header "base/basictypes.h".  We define NOUNROLL256 to reduce the object code
size.

In blapi.h and sha512.cc, replaced uint32 by unsigned int so that they can
be compiled with -DNO_NSPR_10_SUPPORT.  NO_NSPR_10_SUPPORT turns off the
definition of the NSPR 1.0 types int8 - int64 and uint8 - uint64 to avoid
conflict with the same-named types defined in "base/basictypes.h".

rsawrapr.c is copied from nss/lib/softoken/rsawrapr.c, with
HASH_GetRawHashObject changed to HASH_GetHashObject. It contains the
emsa_pss_verify function for verifying RSA-PSS signatures.
