[tex-live] win32

[Fabrice Popineau]

Anybody interested in windows can try the whole suite now. I do not
claim for extensive tests yet, but here is a rough account of the
latest changes:

- kpathsea has been modified to allow for redirection of stderr to
stdout, could be handy for win users. Just set KPATHSEA_DEBUG_OUTPUT
to 'con:'. Also the redirection has been fixed and nested process can
write in the same file (previously resulted in garbage).
- kpathsea shares all its hash tables in memory and no program is
using the standard system()/popen() C calls, but instead a rewrite of
them bypassing the usage of the command interpretor whenever possible.
- TeXSetup.exe: should allow to install even for normal user, but only
in a location where it has rights to do so. Still untested. Privileges
required to install site-wide have been lowered to 'power users' for
NT and above. Installation has been tested against W98.
Config files using .map files lines are edited automatically.
- TeXLive.exe: has its final shape, except that the toggling of
'Internet Access' menu should result in checking for an Internet
connection (left blank for the moment).
