Jay Satiro bb6b521f69 build: Added wolfSSL build script for Visual Studio projects
Added the wolfSSL build script, based on build-openssl.bat, as well as
the property sheet and header file required for the upcoming additions
to the Visual Studio project files.

/*
By default wolfSSL has a very conservative configuration that can result in
connections to servers failing due to certificate or algorithm problems.
To remedy this issue for libcurl I've generated this options file that
build-wolfssl will copy to the wolfSSL include directories and will result in
maximum compatibility.
These configure flags were used in MinGW to generate the options in this file:
--enable-opensslextra
--enable-aesgcm
--enable-ripemd
--enable-sha512
--enable-dh
--enable-dsa
--enable-ecc
--enable-sni
--enable-fastmath
--enable-sessioncerts
--enable-certgen
--enable-testcert
C_EXTRA_FLAGS="-DFP_MAX_BITS=16384 -DTFM_TIMING_RESISTANT"
Two generated options HAVE_THREAD_LS and _POSIX_THREADS were removed since they
are inapplicable for our Visual Studio build.
Regarding the two options that were added via C_EXTRA_FLAGS:
FP_MAX_BITS=16384
http://www.yassl.com/forums/topic423-cacertorgs-ca-cert-verify-failed-but-withdisablefastmath-it-works.html
"Since root.crt uses a 4096-bit RSA key, you'll need to increase the fastmath
buffer size. You can do this using the define:
FP_MAX_BITS and setting it to 8192."
TFM_TIMING_RESISTANT
https://wolfssl.com/wolfSSL/Docs-wolfssl-manual-2-building-wolfssl.html
From section 2.4.5 Increasing Performance, USE_FAST_MATH:
"Because the stack memory usage can be larger when using fastmath, we recommend
defining TFM_TIMING_RESISTANT as well when using this option."
