714f0a445b SCP: Avoid broken regular expression APIs 
If libpcreposix isn't available, we can't fall back to the local
regex.h since the default C runtime on Linux and OS/X implementations
of the regex functionality doesn't ever match regular expressions
with imbedded newlines.

7bcf407fcc TIMER: Reorganize timer control variables to use a structure for each timer 
The original approach had separate parallel arrays for each relevant
state variable for each calibrated timer.  That worked when there were
only a few state variables, the state info for a timer belongs in a
structure.

97bee79faa TIMER: Fix overflow error in sim_idle_ms_sleep() timespec tv_nsec field 
Backed out commit 484889ea5a since the overflow of the timespec tv_nsec
field was the real cause of the problem.  No need for an extra mutex.

484889ea5a TIMER: Changed sim_idle_ms_sleep() to use a mutex which is unique to idling 
It seems that the prior use of sim_asynch_lock RECURSIVE mutex could
cause a pthread_cond_timedwait() failure with EINVAL returned.

2b9ce757fd MINGW: Fix build with newest MinGW tool chain 
Newest Win32 include files changed the include file order as compared to the
Microsoft MS compilers.

This is arguably a bug in the MinGW codebase, but working around it is too trivial
to complain about.

6487d319cd VMS Build: Restore VAX/VMS host build support 
The C RTL on the latest VAX/VMS does not provide a snprintf function.

by Jordi Guillaumes Pons.

932d16da53 SCP: Rework SEND and EXPECT commands to provide default and temporary arguments 
- EXPECT HALTAFTER=nnn
     --> sets "nnn" as the global/default value

 - EXPECT "some string"
     --> uses the "nnn" global/default value

 - EXPECT HALTAFTER=ttt "some string"
     --> uses the "ttt" temporary value for this EXPECT only

and:

 - SEND AFTER=nnn
     --> sets "nnn" as the global/default value

 - SEND "some string"
     --> uses the "nnn" global/default value

 - SEND AFTER=ttt "some string"
     --> uses the "ttt" temporary value for this SEND only

(and similarly for the SEND DELAY value).
