409401c044 Shut up a few clang-analyze warnings about use of uninitialized variables
The functions are all safe, Clang just isn't clever enough to realise
it.

c69fa50d4c Removing 'if' branch from the fix.
This new error shouldn't be distinguishable from other padding errors.
Updating 'bad' instead of adding a new 'if' branch.

4d04cdcd12 Fix RSA mutex fix
Once the mutex is acquired, we must goto cleanup rather that return.
Since cleanup adjusts the return value, adjust that in test cases.

Also, at cleanup we don't want to overwrite 'ret', or we'll loose track of
errors.

88fca3ef0e Fix thread safety issue in RSA operations
The race was due to mpi_exp_mod storing a Montgomery coefficient in the
context (RM, RP, RQ).

The fix was verified with -fsanitize-thread using ssl_pthread_server and two
concurrent clients.

A more fine-grained fix should be possible, locking just enough time to check
if those values are OK and set them if not, rather than locking for the whole
mpi_exp_mod() operation, but it will be for later.

c70b982056 OID functionality moved to a separate module.
A new OID module has been created that contains the main OID searching
functionality based on type-dependent arrays. A base type is used to
contain the basic values (oid_descriptor_t) and that type is extended to
contain type specific information (like a pk_alg_t).

As a result the rsa sign and verify function prototypes have changed. They
now expect a md_type_t identifier instead of the removed RSA_SIG_XXX
defines.

All OID definitions have been moved to oid.h
All OID matching code is in the OID module.

The RSA PKCS#1 functions cleaned up as a result and adapted to use the
MD layer.

The SSL layer cleanup up as a result and adapted to use the MD layer.

The X509 parser cleaned up and matches OIDs in certificates with new
module and adapted to use the MD layer.

The X509 writer cleaned up and adapted to use the MD layer.

Apps and tests modified accordingly
