mod_perl-0.98_03

Changes for version 0.98_03

construct Perl interperter the first time perl_startup is called rather than the second: -slapped self upside head wondering why I did not do this before -now -DAPACHE_SSL for Stronghold or Ben-SSL does not matter -<Perl></Perl> sections work again -ugly avoid_first_alloc_hack is gone!
added `ENVIRONMENT' section to mod_perl.pod
added `PerlSetEnv' configuration directive
back to only PerlHandler enabled by default
if STATIC=1 is configured during 'perl Makefile.PL', Apache::Constants will also be linked static. This is the default on aix and bsdos.
$r->register_callback will now save a pointer to the request_rec rather than doing it in PerlTransHandler
applied patch from Martin Pool <m.pool@pharos.com.au> so we see the real line number if something goes wrong in an Apache::Registry script
now add -I./ and -I$Config{archlibexp}/CORE to EXTRA_CFLAGS for mod_include integration

$r->send_http_header now resets $r->status to 200 after calling send_http_header() to squash double header w/ Location: bug spotted by Jonathan Lieberman
added $r->cgi_header_out so we can _really_ send headers the way mod_cgi does (e.g. Set-Cookie bug spotted by Jonathan Lieberman)

made room for args in perl_call_handler() for mod_include integration in the future, this can be used to pass arguments to Perl*Handlers:
- PerlHandlerArgs Package::sub_name OneArg TwoArg RedArg BlueArg
split out some config routines from mod_perl.c to config.c
fixed bug in Apache/Makefile.PL thanks to Jeff Rowe
now use translate slot to do some initialization
Perl*Handlers can now be anonymous subs (need 5.003_98+), e.g.:
- PerlFixupHandler "sub { shift->header_out(Key => 'val') }"
finally get cleanups right:
PerlCleanupHandler is now run during PerlLogHandler
new method $r->register_cleanup uses register_cleanup underneath and is always available
@INC is now reset to default after each request
fixed "const char *" bug in typemap spotted by Honza Pazdziora
