A general spring-cleaning (in autumn) to fix up signed/unsigned warnings.
...
I have tried to convert 'len' type variable declarations to unsigned as a
means to address these warnings when appropriate, but when in doubt I have
used casts in the comparisons instead. The better solution (that would get
us all lynched by API users) would be to go through and convert all the
function prototypes and structure definitions to use unsigned variables
except when signed is necessary. The proliferation of (signed) "int" for
strictly non-negative uses is unfortunate.

<openssl/evp.h> is now used (MD_DIGEST_LENGTH definitions!).
No need to include such headers directly in md_rand.c.

Change all calls to low level digest routines in the library and
...
applications to use EVP. Add missing calls to HMAC_cleanup() and
don't assume HMAC_CTX can be copied using memcpy().
Note: this is almost identical to the patch submitted to openssl-dev
by Verdon Walker <VWalker@novell.com> except some redundant
EVP_add_digest_()/EVP_cleanup() calls were removed and some changes
made to avoid compiler warnings.

e_os.h does not belong with the exported headers. Do not put it there
...
and make all files the depend on it include it without prefixing it
with openssl/.
This means that all Makefiles will have $(TOP) as one of the include
directories.

Make all configuration macros available for application by making
...
sure they are available in opensslconf.h, by giving them names starting
with "OPENSSL_" to avoid conflicts with other packages and by making
sure e_os2.h will cover all platform-specific cases together with
opensslconf.h.
I've checked fairly well that nothing breaks with this (apart from
external software that will adapt if they have used something like
NO_KRB5), but I can't guarantee it completely, so a review of this
change would be a good thing.

There's a deadlock when ssleay_rand_bytes is called the first time, since
...
it wants to stir the pool using ssleay_rand_add. This fix provides the
possibility to call ssleay_rand_add inside a locked state by simply telling
it not to do any locking through a static variable. This isn't the most
elegant way one could do this, but it does retain thread safety during the
stirring process.

Since ssleay_rand_initialize() unlocks then locks CRYPTO_LOCK_RAND,

it's a good thing if ssleay_rand_status() would do the corresponding
