Fix potential integer overflows in the following functions:
* mbedtls_md2_update() to be bypassed and cause
* mbedtls_cipher_update()
* mbedtls_ctr_drbg_reseed()
This overflows would mainly be exploitable in 32-bit systems and could
cause buffer bound checks to be bypassed.
Fix an incorrect condition in ssl_check_ctr_renegotiate() that compared
64 bits of record counter instead of 48 bits as described in RFC 6347
Section 4.3.1. This would cause the function's return value to be
occasionally incorrect and the renegotiation routines to be triggered
at unexpected times.
This PR fixes a number of unused variable/function compilation warnings
that arise when using a config.h that does not define the macro
MBEDTLS_PEM_PARSE_C.
Add a test to ssl-opt.sh to ensure that in DTLS a 6 byte record counter
is compared in ssl_check_ctr_renegotiate() instead of a 8 byte one as in
the TLS case. Because currently there are no testing facilities to check
that renegotiation routines are triggered after X number of input/output
messages, the test consists on setting a renegotiation period that
cannot be represented in 6 bytes, but whose least-significant byte is 2.
If the library behaves correctly, the renegotiation routines will be
executed after two exchanged.

Fixes strict C99 builds in all.sh with glibc version >2.19 where platform support
wasn't being compiled in automatically.
Also fixes C99 syntax with armclang.
Pull Request #533 - Use MAKEFLAGS to pass args to make in all.sh
Modify the script at tests/scripts/all.sh to export the variable
MAKEFLAGS with -j if it was not set before. This should decrease the
total runtime of tests/scripts/all.sh by letting make run multiple jobs
in parallel. Also, add a check at the top of the script to cause a
failure if the environment is not Linux.w

Changes use of mklink in Windows test builds, to create junctions instead of
directory symbolic links. This removes the need for an elevated command prompt
when running cmake to create the Visual Studio project files.
Tighten up the test options in all.sh, test-ref-configs.pl and curves.pl
to ensure the builds are strict for all warnings, warnings are treated
as errors, and that wherever possible builds are strict to the C99
standard. (Note that builds that use the Unix sockets API cannot be).
Fixes many typos, and errors in comments.
* Clarifies many comments
* Grammar correction in config.pl help text
* Removed comment about MBEDTLS_X509_EXT_NS_CERT_TYPE.
* Comment typo fix (Dont => Don't)
* Comment typo fix (assure => ensure)
* Comment typo fix (byes => bytes)
* Added citation for quoted standard
* Comment typo fix (one complement => 1's complement)
The is some debate about whether to prefer "one's complement", "ones'
complement", or "1's complement". The more recent RFCs related to TLS
(RFC 6347, RFC 4347, etc) use " 1's complement", so I followed that
convention.
* Added missing ")" in comment
* Comment alignment
* Incorrect comment after #endif
