3ff49fc9b2 Fixed build errors, remove dependency on std. 
Build errors: Include guard missing from epicsUnitTest.h;
    dbShutdownTest.c was calling the non-universal strcasecmp()
    instead of epicsStrCaseCmp().

ioc/db/test no longer depends on std. I modified
    xRecord to make it a working record type, and simplified the
    other test programs so they all use the same new expanded
    dbd file rather than each making their own. I also added
    dbShutdownTest() to epicsRunDbTests().

60a0c7f181 Make epicsExit subsystem reusable. 
Calling epicsAtExit() after epicsExitCallAtExits() now
recreates the per-process list and registers the routine.

f5b9db9583 libCom: Fix epicsString.h comparison functions 
The string comparison functions epicsStrCaseCmp() and
epicsStrnCaseCmp() were returning incorrect results
when the strings did not match.

These functions now match their BSD equivalents, and
have working tests to confirm their operation.

5bdd9ddca6 Windows: Fix static builds on MinGW

the MinGW targets to succeed. Some additional changes made to
blockingSockTest.cpp also clean that up.

a3354f5db9 libCom: NTP Time Provider adjusts to OS tick rate changes 
Allow the NTP Time provider (used on VxWorks and RTEMS only)
to adapt to changes in the OS clock tick rate after the provider
has been initialized.

Changing the tick rate after iocInit() is not advisable,
other software might still misbehave if initialized before
an OS tick rate change.

e1e389a2dd Low-memory behaviour fixes. 
Fix unchecked buffer allocation in dbChannel.c

things that happen often after iocInit.

Michael Davidsaver pointed out this issue.

b32127c5de libCom: Fix epicsTime::strftime() roll-over bug 
Fractional seconds could round-up to .000 without
incrementing the integer seconds.
We can't actually do the latter, so we prevent the
roll-over and clamp at all 9's instead.
Idea from Eric Norum.
