6483af8e42 Fix the broken pkcs1 v1.5 test. 
The random buffer handed over to the test function was too small
and the remaining bytes were generated by the default (platform
dependant) function.

8eeecd0444 Fix the backport of pkcs1 v1.5 test suite. 
The test suite was not properly backported and it remained unnoticed,
because it was not compile due to the change in the naming of the
compile time requirements.

f18263d78b Removing 'if' branch from the fix. 
This new error shouldn't be distinguishable from other padding errors.

7244ecf52e Add tests for the bug IOTSSL-619. 
The main goal with these tests is to test the bug in question and
they are not meant to test the entire PKCS#1 v1.5 behaviour. To
achieve full test coverage, further test cases are needed.

a91d85e331 Fix for net_usleep() timing selftest on mingw 
In mingw32, net_usleep() was failing to sleep for the given period, and was
sleeping in microseconds, not milliseconds. Fix backported from mbed TLS 2.x of
using the Win32 Sleep() API call rather than using the timeout of select().

20715dc73b Make ar invocation more portable 
armar doesn't understand the syntax without dash. OTOH, the syntax with dash
is the only one specified by POSIX, and it's accepted by GNU ar, BSD ar (as
bundled with OS X) and armar, so it looks like the most portable syntax.

cf16b79238 Avoid seemingly-possible overflow 
By looking just at that test, it looks like 2 + dn_size could overflow. In
fact that can't happen as that would mean we've read a CA cert of size is too
big to be represented by a size_t.

However, it's best for code to be more obviously free of overflow without
having to reason about the bigger picture.

c05014459e Fix wrong length limit in GCM 
See for example page 8 of
http://csrc.nist.gov/publications/nistpubs/800-38D/SP-800-38D.pdf

The previous constant probably came from a typo as it was 2^26 - 2^5 instead
of 2^36 - 2^5. Clearly the intention was to allow for a constant bigger than
2^32 as the ull suffix and cast to uint64_t show.

c4a47e3483 Fix bug checking pathlen on first intermediate 
Remove check on the pathLenConstraint value when looking for a parent to the
EE cert, as the constraint is on the number of intermediate certs below the
parent, and that number is always 0 at that point, so the constraint is always
satisfied.

The check was actually off-by-one, which caused valid chains to be rejected
under the following conditions:
- the parent certificate is not a trusted root, and
- it has pathLenConstraint == 0 (max_pathlen == 1 in our representation)

fixes #280
