44bfd68a45 PDP11, VAX: Fix DMA output timing to properly track programmed speeds 
Always start DMA activity when TBUFAD2 is written, either FAST (vh_wait/10)
or slow vh_wait.

Possibly related to #578 and #588 issues

173e1bf073 Visual Studio Projects: Migration to normalized windows-build support 
- All projects use identical include directories, library definitions and
   library directories.
- Remove attempts to add XP support to projects that were converted to
   .vcxproj for post VC2008 versions of Visual Studio.
- Require that git be available when building within a git repository
   working directory.

aea7f208cf PDP11, VAX: Rework VH transmit start and completion timing 
Programmed and DMA I/O now presents data into the line output queue and
schedules all refill and/or I/O completion in the unit service routine.

d3da865e9b TMXR: Fix MUX transmit scheduling when buffer is empty

- Allow BPS factor to change without specifying an explicit speed.

c73f56cc5a PDP11, VAX: Add descriptive unit names to DZ, RQ, TQ, XQ and XU devices 
Some devices have dedicated units that perform various independent
functions (often timing) that are independent of the primary device unit
which is ATTACHed.  This services to help interpret debug information
that may be produced.

91bd90c368 PDP11, VAX: Change VH programmed I/O to consistently complete after delay 
previously, programmed I/O was initiated and completed as the time it was
initiated.  Now that output is rate limited to the port selected speeds the
output buffer can fill and I/O be dropped when the buffer was full.  Now all
output is setup in the register write path and completed in the unit service
path.  A separate transmit service unit now performs all transmit I/O
completion activity.
