Merged J. Lewis Muir's fix for comments introduced by macro.
Added fixes to allow comments to be indented too, which used
to work if the '#' was followed by white-space or any argument
separator character.
The handling of comment lines is only performed before macro
expansion, thus lines with macros that expand to comment lines will
not be correctly handled as comment lines.
By chance this kind of worked sometimes because a "#" command that
does nothing is internally added to the command registry to make it
show up in the help output. Relying on this is broken. Furthermore,
if the line starts with '#' followed by a non-separator character
(e.g. "##", "#whatever", etc.) it will not work (i.e. it will produce
a command-not-found error).
This fix checks to see if the first character of the line after macro
expansion is '#'. If it is, it considers the line to be a comment.
replaced the osdSysTime provider with a new osiClockTime provider,
stringin device support puts record into alarm if no working provider,
added osdTimeRegister() to RTEMS/osdTime.h.
* Added new monitoring API with insert and remove callbacks; the old API is
still supported though.
* Added report routine, callable from iocsh.
* taskwdInsert() can take a NULL tid, meaning the calling thread.
