If we enabled AES_DECRYPT_ALT and either AES_SETKEY_DEC_ALT or
AES_USE_HARDWARE_ONLY, this means RSb and RTx are not needed.
This commit extends how we guard RSb and RTx for the combinations of
these configurations.

If MBEDTLS_BLOCK_CIPHER_NO_DECRYPT is enabled, but decryption is
still requested in some incompatible modes, we return an error of
FEATURE_UNAVAILABLE as additional indication.

This changes local variable name RCON to round_constants.
RCON being definition in xc32 compiler headers for some PIC32 register.
Without this change, mynewt project for PIC32 platform fails to build due to
macro redefinition.
This does not changes behavior of library in any way.

with introduction of MBEDTLS_AES_NEED_FORWARD_S_BOXES and

Variable RSb is only used for either computing reverse tables
in aes_gen_tables or AES-decryption function. This commit provides
more guards for when RSb is defined and used.

If passed a zero length, AES CBC could potentially corrupt the passed
in IV by memcpying it over itself. Although this might be ok with
more recent compilers, its not for every compiler we support. Found
by coverity.

`MBEDTLS_AESNI_C` does not depends on `MBEDTLS_HAVE_ASM`
when intrinsic is available.
And compiler relative checks only work on x86_64, it should
be only checked on x86_64.

The link to the DRBG paper points to the March 2007 version, the same as the
original link (rather than the latest version).
The amended Rijndael paper has a two-page "Note on naming" prefix.
