This should be fix the bug that apache enabled SSL may exhaust its
file descriptors. Noted by TAKANO Yuji <takachan@running-dog.net>
on apache@ecc.u-tokyo.ac.jp, apache mailing list in Japanese.
He had already sent a bug report to openssl-dev@openssl.org, but it
wasn't fixed in openssl-0.9.6. :-(
don't use unsigned long where 32bit unsigned variable is asked for.
use u_int32_t. (not sure if uint32_t is better or not, but anyway,
u_int32_t <-> uint32_t should not raise binary compatibility issue)

TODO: have arch-dependent Makefiles where we supply -DFOO for optimization.
(do not change size of variable though)
XXX: we should actually nuke all other #ifdef in /usr/include/openssl/*.h,
however, that needs a lot of work and will make future openssl upgrade harder.
remove RC5 and IDEA by default. build them separately as
libcrypto_{rc5,idea}.a. put dummy function, which is "warning to stderr
and exit(1)". NOCRYPTO_{RC5,IDEA} are obsoleted.
