Érico NogueiraandMichael Davidsaver 7c4a21eab4 libCom: detect support for backtrace() with __has_include. 
This is necessary in order to build epics-base with musl libc, for
example, and any other C libraries which don't include this
functionality. In order to not regress builds with older compilers, we
still support the uclibc check. Furthermore, it has been checked that
uclibc-ng (the maintained version of uclibc) doesn't install the
<execinfo.h> header when the functionality is disabled [1] [2].

To avoid repetition, we don't define HAS_EXECINFO to 0 when it is not
available.

Michael Davidsaver fab8fd7102 dbEvent: handle multiple db_event_cancel() 
Allow for multiple db_event_cancel() (concurrent or
self-cancel) prior to event_task wakeup.

In db_event_cancel(), immediate free() only if idle
(not queued or in progress).  Otherwise, defer free()
to event task.  Avoids need to immediately expunge
canceled event from queue.  Allow event task to
process canceled events as normal (except no user_sub)
until npend==0.

MinijacksonandMichael Davidsaver d87fd0db01 Fix MAKEFLAGS parsing with Make 4.4+ 
Since Make version 4.4, MAKEFLAGS also contains long options and
overridden variables on the command-line[1].

[1]: https://git.savannah.gnu.org/cgit/make.git/tree/NEWS?h=4.4#n67

This means that parsing by filtering out '--%' doesn't work reliably
anymore, since it doesn't remove overrides:

Running 'make VAR=quacks' gives 'MAKEFLAGS=" -- VAR=quacks"', and
'checkflags' would understand that flags -q, -s, ... were set.

This would get transmitted below into 'QUIET_FLAGS' and
'QUESTION_FLAG', then passed to the 'genVersionHeader.pl' as '-i' and
'-q'.

The result would be that 'genVersionHeader.pl' would never create the
version header (only check for its up-to-date status), leading to
confusing errors:

  ../misc/epicsRelease.c:25:32: error: expected ')' before 'EPICS_VCS_VERSION'
     25 |     printf ( "## %s\n", "Rev. " EPICS_VCS_VERSION );
        |            ~                   ^~~~~~~~~~~~~~~~~~

The NEWS file[1] recommends using 'firstword', but unfortunately this is
not compatible with GNUMake < 3.82.

Sebastian MarschingandMichael Davidsaver 3a2d225682 Detect error in fprintf and return (fixes #309). 
fprintf returns a negative value in order to signal an error. We have to
detect this situation in epicsStrPrintEscaped and return a negative
when fprintf returns a negative value in order to give the calling code
a chance to detect this situation.

The old implementation (of simply accumulating the return values of
fprintf) was wrong anyway, because it would not only lead to an error in
fprintf to be lost but would also cause the returned number to be too
small (not representing the actual number of bytes written) in such a
case.

The only case where the old implementation would work correctly was when
all calls to fprintf succeeded or all these calls failed.
