Add C native types macro helpers
The SIDE ABI specifies fixed sizes integers and floating points.
However, as a convenience for C/C++, the SIDE C API supports C native
types (e.g. char) which are translated to their equivalent.
Note that the translation of C native types is toolchain dependent and
therefore could produce different results.
The main use case is for auto-generating SIDE events for public API of
shared libraries.

fix: handle EINTR correctly in get_cpu_mask_from_sysfs
If the read() in get_cpu_mask_from_sysfs() fails with EINTR, the code is
supposed to retry, but the while loop condition has (bytes_read > 0),
which is false when read() fails with EINTR. The result is that the code
exits the loop, having only read part of the string.
Use (bytes_read != 0) in the while loop condition instead, since the
(bytes_read < 0) case is already handled in the loop.

Use event state as argument to call fast path
Eliminate the need to load the event description cache lines (to load a
pointer to the event state) on the fast path by passing a pointer to the
event state as argument to the call.

trace.h: Move back nr_callbacks to event description
nr_callbacks is not used on the fast path, therefore move it back to the
event description to optimize cache density of the event state enabled
flags.
