[pubcookie-dev] Security context fixup for Win32

[Ryan Campbell]

There should only be four minor changes outside of the Win32 #ifdefs in
security_legacy.c:

! pbc_cookie_data *libpbc_unbundle_cookie(pool *p, const security_context
*context, char *in, const char *peer, const char use_granting)

(to make definition consistant with declaration)


!     fp = pbc_fopen(p, cryptkey, "rb");

(Windows needs the b for binary files, POSIX ignores it)

!     if( cb_read = fread(context->cryptkey, sizeof(char),
PBC_DES_KEY_BUF, fp)
!= PBC_DES_KEY_BUF) {
          pbc_log_activity(p, PBC_LOG_ERROR,
!                       "can't read crypt key %s: short read: %d", cryptkey,
cb_read);

(cryptkey was mistakenly keyfile, added cb_read for extra debugging)

!         strlcat(buf, DIR_SEP, 1024);

(Windows likes backslash)



Note that I've not yet implemented different security contexts for the
filter.  I'll get on that next.

I also had to lose some typchecking and typedef pool to void due to an
include file catch-22.  I'll try to repair that as well.
