Make it clear that the recorder_ring_compare_exchange macro updates
the head in place with the new value, because it uses
the __atomic_compare_exchange_n primitive, which does, as documented in
https://gcc.gnu.org/onlinedocs/gcc/_005f_005fatomic-Builtins.html

This compares the contents of *ptr with the contents of *expected.
If equal, the operation is a read-modify-write operation that writes
desired into *ptr.
If they are not equal, the operation is a read and the current contents
of *ptr are written into *expected.

Changes in this release:
- License clarification (LGPLv3 for the library components)
- Improved portability on Windows platforms (MinGW, MSYS and Cygwin)
- Record scope has the ability to toggle display modes using keys
- Various minor fixes and improvements
- Welcoming a new contributor to the code (Frediano Ziglio)

This makes these two look more like function calls.
The existing macros still work for obvious compatibility reasons.

The old carried-over headers still had remnants of GPL in them.
Convert to LGPLv3 for what goes in the library, GPLv3 for the rest.

NOTE: This may not be the final change. If this is to be used
in LGPLv2.1 projects like SPICE, the current setup may not be
correct, as indicated the license compatibility matrix at
https://www.gnu.org/licenses/gpl-faq.html#AllCompatibility.

The intent of the authors is to make the code license-compatible,
and further licensing changes may be required to that effect.

Some MinGW variants have it, some don't (MSYS2 MinGW64 environmnent)

This breaks on some MinGW variants with:
recorder.c: In function "recorder_trace_set":

On MinGW, regex will be  in /mingw32/lib/libregex.a.
Apparently, it's also possible to use pcre2

This is in case MinGW someday fixes their drand48 situation.
Also, it happens that I was using drand48, which was not adjusted for.

I see this appear on an old Win7 machine

Without precisely tracking if axis is already attached, you get:

"Can not add axis. Axis already on the chart."
