Right-aligning backslashes when defining macros or using complex
commands in Makefiles looks cute, but as soon as any changes is
required to the code you end up with either distractingly broken
alignment or unnecessarily big diffs where most of the changes
are just pushing all backslashes a few characters to one side.

There were a few places in our code where the following pattern in 'if'
condition occurred:

if ((foo = bar() < 0))
    do something;

This patch adjusts the conditions to the expected format:

if ((foo = bar()) < 0)
    do something;

With gnutls 3.6.0, SHA1 is no longer accepted for certificate
signatures. We must usw SHA256 instead.

In gnutls 3.4.3 there is a regression in the loading of private
keys via gnutls_x509_privkey_import. We already have a workaround
to deal with failures on older gnutls, but the error code that
the new gnutls returns is different. Extend the workaround so that
is checks for GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE too.

Assign the value we're comparing:
(val = func()) < 0
instead of assigning the comparison value:
(val = func() < 0)

Both were introduced along with the code,
the TLS tests by commit bd789dff in 0.9.4
net events by commit de87691f in 1.2.2.

Note that the event id type fix is a no-op:
vshNetworkEventIdTypeFromString can only return
-1 (failure) and the event is never used or
0 (the only possible event) and the value of 0 < 0 is still 0.

Any source file which calls the logging APIs now needs
to have a VIR_LOG_INIT("source.name") declaration at
the start of the file. This provides a static variable
of the virLogSource type.

Use a separate keyfile name for the two TLS test suites so that
they don't clash when running tests in parallel

The code added to validate CA certificates did not take into
account the possibility that the cacert.pem file can contain
multiple (concatenated) cert data blocks. Extend the code for
loading CA certs to use the gnutls APIs for loading cert lists.
Add test cases to check that multi-level trees of certs will
validate correctly.

Currently every test case in the TLS test suite generates the
certs fresh. This is a waste of time, since its parameters
don't change across test cases. Create certs once in main
method.

The virnettlscontexttest.c tests both virNetTLSContext
and virNetTLSSession functionality. Split into two
separate tests, to make the code size more manageable
