Jeremy LorelliandAndrew Johnson bd8c35d8e7 Implement epicsMessageQueueSend/epicsMessageQueueReceive to resolve link error 
These were defined as macros in osdMessageQueue.h, but declared as
prototypes in epcisMessageQueue.h public header. We need to implement
them as C functions for these to actually be usable.

Érico NogueiraandAndrew Johnson 21368dc7b4 Don't include linux/ header in osdSockUnsentCount. 
Per the manpage in the file's comment, SIOCOUTQ is equivalent to the
TIOCOUTQ ioctl, whose value can be obtained by including <sys/ioctl.h>,
which allows us to avoid including any system-specific headers. This is
desirable so that, on a musl system, it won't be necessary to install
kernel headers in order to build epics-base.

Since it's first been checked into Git, the Linux kernel has defined
SIOCOUTQ to be TIOCOUTQ [1].

From the three main libc options on Linux: glibc and uclibc use the
kernel headers, so both ioctls are available; and musl defines only
TIOCOUTQ in their own headers.

Michael DavidsaverandAndrew Johnson 48ebe2c64e Avoid initMainThread() except on vxworks 
Move isOkToBlock tracking to osdThread.
Targets except vxworks can store this flag in epicsThreadOSD.
Continue to use TLS w/ vxWorks.

Note that setting of isOkToBlock for "main" thread becomes lazy.

Jeremy LorelliandMichael Davidsaver 721e9cc3a7 Add ABORT_ON_ASSERT flag to CONFIG_SITE 
This flag causes EPICS to call abort() on assertion failures rather than
suspend the executing thread. With the epicsThreadSuspendSelf() behavior,
an IOC can end up in a difficult to detect error state where one or more
threads has essentially crashed due to an assertion failure.

This also matches the C behavior of assert(3)

Freddie AkeroydandAndrew Johnson 4720b61c1f Move call to setThreadName() 
The call to setThreadName() is moved to avoid a race condition that
can happen with very short lived processes. If the process terminates
very quickly e.g. is a google test runner or the msi.exe command
called from a Makefile during a build, then very occasionally a
crash can occur during process termination if setThreadName() when called
from the newly created thread. This looks to be becauae the DLL it is
trying to call gets unloaded between it getting a handle to the DLL
and making the call. Moving the setThreadName() call to the creating
thread avoids this problem. The issue was only ever seen with statically
linked epics executables, I am unsure if the way a DLL based epics
program unloads might avoid this, or just make it less likely but
still possible. As mentioned above, the issue will only ever occur
to threads that are created during process termination and so would
not affect running IOCs

Érico Nogueiraandzimoch 49b9573f3a 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.
