to avoid file names which are two long for the standard GNU/Linux file systems.

A simple 'sleep' is more reliable.

then synchronize the file system to ensure all links are flushed before
compilation starts

Uses the 'wait -n' builtin to avoid the use of non-POSIX 'sleep' commands

Ensures the order of compilation relates to the location of the source files

and added support for queue scheduling option '-q', '-queue'

Now the 'Allwmake' scripts execute 'wmake -all' to handle parallel
processing in a general way, avoiding code duplication.

wmakeCollect collects the compilation commands for the all of the object
files to be compiled into a single makefile which is passed to make to
schedule the compilations in parallel efficiently.

Before wmakeCollect can be called the lnInclude directories must be
up-to-date and after wmakeCollect the linkage stage of the compilation
must executed using wmake.

This entire process is now handled by wmake using the new '-queue' or
'-q' option to compile sections of the OpenFOAM source tree or the
entire tree efficiently.  The number of cores the compilation executes
on may be specified either using the WM_NCOMPPROCS variable or the '-j'
option.

To efficiently compile OpenFOAM after a 'git pull' the '-update' option
is provided which updates lnInclude directories, dep files and removes
deprecated files and directories.  This option may be used with '-q':

    wmake -q -update
