Fix MSVC compile issue in chacha.c.
...
MSVC generates a syntax error when you initialize
an array with {}. {0} has the same effect and compiles.

rename wc_XChaCha_init() to wc_XChacha_SetKey() for consistency, and add a counter argument to provide for future random access scenarios; refactor wc_Chacha_purge_current_block() to use a dummy wc_Chacha_Process() call for intrinsically correct counter dynamics.

Fix for Curve25519 FE math build error with Intel Speedups enabled and no AVX2. Fixes to allow forcing NO_AVX2_SUPPORT. Reproducible with ./configure --enable-curve25519 --enable-ed25519 --enable-intelasm CFLAGS="-DNO_AVX2_SUPPORT".

Rename INLINE

1. Renamed the macro INLINE as WC_INLINE.
2. For FIPS and the "selftest" build, define INLINE as WC_INLINE. Allows the FIPS code to work unchanged.

Changes for interop and performance
...
Changes made to test.h to allow interop of PSK with OpenSSL.
Changes to allow server to pre-generate key share and perform other
operations at later time.
Fix ChaCha20 code header to have bigger state to support assembly code
for AVX1.
Fix Curve25519 code to use define instead.
Change Curve25519 to memset all object data on init.
Change Poly1305 to put both sizes into one buffer to avoid a second call
to wc_Poly1305Update().
Added WOLFSSL_START and WOLFSSL_END API and calls to show time of
protocol message function enter and leave to analyse performance
differences.
Moved Curve25519 code in KeyShare extension out of general ECC code.

Improve performance of chacha20-poly1305 on AVX and AVX2.
...
Create an AVX2 version of the small block size chacha20 encryption code.
Only update the poly1305 once for the two lengths in chacha20-poly1305.
Poly1305 AVX2 uses AVX code to handle last bytes, store H whole.
Fix error codes in poly1305 test and add a longer data test case.
