Agustin Gianni 48116c2d0f Fix incorrect use of BN_CTX API
In some edge cases BN_CTX_end was being called without first calling
BN_CTX_start. This creates a situation where the state of the big
number allocator is corrupted and may lead to crashes.

Fixes #13812

Dr. Matthias St. Pierre 706457b7bd Reorganize local header files
Apart from public and internal header files, there is a third type called
local header files, which are located next to source files in the source
directory. Currently, they have different suffixes like

  '*_lcl.h', '*_local.h', or '*_int.h'

This commit changes the different suffixes to '*_local.h' uniformly.

Matt Caswell 2934be9134 Make sure all BIGNUM operations work within the FIPS provider
The FIPS provider does not have a default OPENSSL_CTX so, where
necessary, we need to ensure we can always access an explicit
OPENSSL_CTX. We remove functions from the FIPS provider that use
the default OPENSSL_CTX, and fixup some places which were using
those removed functions.

Geoff Thorpe b6358c89a1 Convert openssl code not to assume the deprecated form of BN_zero().
Remove certain redundant BN_zero() initialisations, because BN_CTX_get(),
BN_init(), [etc] already initialise to zero.

Correct error checking in bn_sqr.c, and be less wishy-wash about how/why
the result's 'top' value is set (note also, 'max' is always > 0 at this
point).
