4815752ccc Add Perl interface to C storage layer.
Maintaining the storage layer/drivers in two languages is burdensome.  Since the integration tests require the Perl storage layer/drivers we'll need them even after the core code is migrated to C.  Create an interface layer so the Perl code can be removed and new storage drivers/features introduced without adding Perl equivalents.

The goal is to move the integration tests to C so this interface will eventually be removed.  That being the case, the interface was designed for maximum compatibility to ease the transition.  The result looks a bit hacky but we'll improve it as needed until it can be retired.

8c712d89eb Improve type safety of interfaces and drivers.
The function pointer casting used when creating drivers made changing interfaces difficult and led to slightly divergent driver implementations.  Unit testing caught production-level errors but there were a lot of small issues and the process was harder than it should have been.

Use void pointers instead so that no casts are required.  Introduce the THIS_VOID and THIS() macros to make dealing with void pointers a little safer.

Since we don't want to expose void pointers in header files, driver functions have been removed from the headers and the various driver objects return their interface type.  This cuts down on accessor methods and the vast majority of those functions were not being used.  Move functions that are still required to .intern.h.

Remove the special "C" crypto functions that were used in libc and instead use the standard interface.

2ef5ad70a2 Move crypto module to common/crypto.
It makes sense for the crypto code to be in common since it is not pgBackRest-specific.

Also combine the crypto tests into a single module.

7df7cf6e6d Rename cipherBlock*() functions to cipherBlock*C().
Some of the old names conflict with the new functions that must be created to implement the filter. Rename these to cipherBlock*C() to indicate that they take C-style parameters.

These functions are only used by the Perl LibC code and will be removed or refactored eventually.

48d2795f31 Merge crypto/random module into crypto/crypto.
There wasn't enough code to justify a separate module/test and it seems to fit just fine in crypto/crypto.
