NRPE_NT Code

Files in doc has been moved to sourcetree root,
updated the project file to reflect the changes.

Source has actually been broken for several years:
It has subtracted the used RAM from the used page file without
accounting for the non paged RAM. This may lead to negative numbers,
often directly after reboot. Solve by subtract the non paged RAM, if
we can get it, and make sure that the used swap is not negative.

M plugins/wts_load/wts_load.cpp

Replaced bzero with memset.

Added svn:executable property for autogen.sh

* Added evlog.h for use with mingw due to it seems to be
no tools available for generating on from evlog.mc

* Removed evlog.h from svn:ignore property

Added leftout ChangeLog file

* Removing src/sample due to content is moved into root of sourcetree

* Added leftout COPYING file to make autogen.sh happy

Remove of directory due to autoconfification moved the files into
sourcetree root where it is expected to be.

* Autoconfification

* Fixes for mingw compilations of source

* evlog.h is checked in, even though it should really be generated
with "mc". However, MinGW doesn't provide a mc tool, it seems.

BIG REVERT, basically back to r43. The reason for this is that r44 and
r45 did huge changes with an empty log message. These two commits also
broke a lot of things. Some of these have been again fixed in later
revisions, but not all. In detail, this reverts does:

* Changes back the timestamp logging code. The CHANGELOG says "fixed
timestamp in nrpe_nt.log", but I don't see what wrong with the
earlier code.

* Removed the loglevel config param. Hard to exclude from the
revert. If only this feature had been atomically committed from the
beginning...

* Reverts the file version, to avoid any confusion. We will bump up to
a new major in a near future.

* Reverted the handling of argument characters (ALLOWED_ARGUMENT_CHARS
vs NASTY_METACHARS and NASTY_METACHARS_WIN). Again, the commit
contained no motivation whatsoever why this change was done.

* Again supporting prefetch commands.

* Removed the delay_shutdown feature. Again, hard to exclude, and
there's no real motivation for it.
