[Openvpn-devel,1/7] Remove option to disable crypto engine

  With this patch we remove the possibility to disable the crypto engine
(ENABLE_CRYPTO define) at configuration time.

[Some unit-test are temporarily disabled and will be enabled again when
ENABLE_CRYPTO is completely removed from the codebase]

[--disable-crypto has been removed from .travis.yml too]

Hi,

Feature-ACK.

As discussed on IRC, let's apply this patch after 2/7 (or merge with
2/7) to prevent having a commit in the tree that unconditionally
disabled crypto.

Why rename this (and ENABLE_CRYPTO_MBEDTLS)?  All our configure feature
flags currently have this ENABLE_ prefix, and I'd personally prefer to
keep it for these too.  (Though I don't care enough to NAK.)

I decided to remove the ENABLE_* bit because it felt to me like those
ENABLE_CRYPTO_$SOMETHING were "subdefines" of ENABLE_CRYPTO.

However, for consistency with the rest I also agree that it would be
better to keep the ENABLE_ prefix.

I'll send v2 of this patch only where I'll reintroduce the prefix.


Thanks!
