Declare an explicit Python version. Pick 3.5 which is the default
version on Ubuntu 16.04. This is necessary on Travis to have a working
pip for Python 3.
Install Pylint 2.4.4. There's nothing special about this version, it's
just the latest version.

Split the build between:
* Basic checks
* A build in the default configuration with extensive tests
* Builds in other configurations with less testing
The intent is to have one shorter job with basic tests, and two longer
jobs that take roughly the same amount of time (split as evenly as
possible while keeping an easy-to-understand separation).

In practice, we hardly ever get different outcomes, so there is no
gain in running tests with different compilers.
Experimentally, with the builds and tests we currently do and with the
compiler versions on a Travis Ubuntu 16.04, gcc jobs are significantly
faster than clang jobs (13 min vs 24 min). So use gcc.

Make it possible to use a compiler that isn't in $PATH, or that's
installed with a different name, or even a compiler for a different
target such as arm-linux-gnueabi.

Almost everything the selftest program does is in the test suites. But
just in case run the selftest program itself once in the full
configuration, and once in the default configuration with ASan, in
addition to running it out of box.

When parsing a certificate with the basic constraints extension
the max_pathlen that was read from it was incremented regardless
of its value. However, if the max_pathlen is equal to INT_MAX (which
is highly unlikely), an undefined behaviour would occur.
This commit adds a check to ensure that such value is not accepted
as valid. Relevant tests for INT_MAX and INT_MAX-1 are also introduced.
Certificates added in this commit were generated using the
test_suite_x509write, function test_x509_crt_check. Input data taken
from the "Certificate write check Server1 SHA1" test case, so the generated
files are like the "server1.crt", but with the "is_ca" field set to 1 and
max_pathlen as described by the file name.

When building with MBEDTLS_MEMORY_DEBUG enabled, and running the ecdh part,
the benchmark program would start writing a very large number of space
characters on stdout, and would have to be killed because it never seemed to
terminate.
This was due to an integer overflow in computing how many space to leave after
the title in order to get memory measurements aligned, which resulted in up
to SIZE_MAX spaces being printed.
This commit just fixes the overflow, the next commit is going to fix the magic
number (12).

To test a file name exactly, prepend a / to the base name.
files_to_check actually checks suffixes, not file names, so rename it
to extensions_to_check.

The identifiers of the unmet dependencies of a test case are
stored in a buffer of fixed size that can be potentially too
small to store all the unmet dependencies. Indicate in test
report if some unmet dependencies are missing.

Adding .function was necessary, as otherwise ctags would have no idea what to
do with those files.
Adding .h may not be necessary, as by default ctags considers them C++ which
is probably good enough, but since we're tuning the mapping anyway...

See the comments in the code for how an attack would go, and the ChangeLog
entry for an impact assessment. (For ECDSA, leaking a few bits of the scalar
over several signatures translates to full private key recovery using a
lattice attack.)

We keep track of the current epoch and record sequence number in out_ctr,
which was overwritten when writing the record containing the
HelloVerifyRequest starting from out_buf. We can avoid that by only using the
rest of the buffer.
Using MBEDTLS_SSL_MAX_CONTENT_LEN as the buffer size is still correct, as it
was a pretty conservative value when starting from out_buf.
Note: this bug was also fixed unknowingly in 2.13 by introducing a new buffer
that holds the current value of the sequence number (including epoch), while
working on datagram packing: 198594709b

The current logging was sub-standard, in particular there was no trace
whatsoever of the HelloVerifyRequest being sent. Now it's being logged with
the usual levels: 4 for full content, 2 return of f_send, 1 decision about
sending it (or taking other branches in the same function) because that's the
same level as state changes in the handshake, and also same as the "possible
client reconnect" message" to which it's the logical continuation (what are we
doing about it?).
