Fedora 30 / gcc 9.1.1 20190503 (Red Hat 9.1.1-1) fails to build
because of this error/warning:
> gstreamer-encoder.c: In function 'set_video_bit_rate':

> gstreamer-encoder.c:518:17: error: absolute value function 'abs'
> given an argument of type 'uint64_t' {aka 'long unsigned int'}
This patches solves these two warnings:
1) cast the substraction to a signed type (int64_t instead of
uint64_t) to preserve the operation meaning;
2) use a custom version of abs() to avoid data truncation and/or
platform-dependent type lengths (abs/labs/llabs)

Code dealing with nanosecond timestamps normally uses 64 bit integers
and not long long ints. So this makes it easier to print the value of
expressions using these constants.

This constant fits in a regular 32 bit signed integer so it does not
need the suffix.
It is also not used in expressions that may overflow.

Bugs such as https://bugzilla.redhat.com/show_bug.cgi?id=1651882 can be
quite tricky to figure out without the detailed OpenSSL error. This
commit adds a detailed dump of the OpenSSL error stack when an OpenSSL
failure happens.
In the bug above, this would have displayed:

This is a thin wrapper over g_get_monotonic_time_ms, and is called only
once, so we can call directly g_get_monotonic_time_ms instead.

There's no reason to change data passed, the function just check
the alpha channel of the image.

spice_server_set_channel_security() is already mostly doing that. We can
make its code more generic, and introduce a red_channel_get_name()
method. This method will then be used to make debug messages more
readable by showing the actual channel name rather than its type as
an int.

This is a generic function not tied to the red_xxx functionality and the
new name clarifies that it returns the time in nanoseconds (unlike
g_get_monotonic_time()).
