Convert KWSys to OSI-approved BSD License
...
This converts the KWSys license to a pure 3-clause OSI-approved BSD
License. We drop the previous license clause requiring modified
versions to be plainly marked. We also update the KWSys copyright to
cover the full development time range.

ENH: Provide unix-sytle command line parsing
...
Add System_Parse_CommandForUnix to the KWSys System interface as a
utility to parse a unix-style command line. Move the existing
implementation out of ProcessUNIX. Add a flags argument reserved for
future use in providing additional behavior.

ENH: Teach KWSys Process basic VMS support
...
This achieves basic process execution on OpenVMS. We use work-arounds
for different fork()/exec() behavior and a lack of select().
VMS emulates fork/exec using setjmp/longjmp to evaluate the child and
parent return cases from fork. Therefore both must be invoked from the
same function.
Since select() works only for sockets we use the BeOS-style polling
implementation. However, non-blocking reads on empty pipes cannot be
distinguished easily from the last read on a closed pipe. Therefore we
identify end of data by an empty read after the child terminates.

BUG: Fix non-select process impl without timeout

BUG: Handle case when select() lies
...
According to "man select" on Linux it is possible that select() lies
about data being ready on a pipe in some subtle cases. We deal with
this by switching to non-blocking i/o and checking for EAGAIN. See
issue #7180 .
