NRPE_NT Code

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.
