apr_socket_send() can return both an error and data, account for data in
the latter case (i.e. let next call fail, if any).

We can destroy ap_pglobal because clean_child_exit() runs in DSO which would be
unloaded under us, so use atexit() to differ the final apr_terminate().

Reverts pre_config hook from r1656669 (happens too late for EXEC_ON_READ), and
ensures ap_macros is reset on restart with a pconf cleanup.

As suggested by Joe, add --maintainer/debugger-mode's CFLAGS in
NOTEST_CFLAGS to avoid interractions with autoconf's AC_LANG_PROGRAM.

APACHE_ADD_GCC_CFLAG now also forces -Wno-strict-prototypes for -Werror
to work despite AC_LANG_PROGRAM generating this warning by itself.

Setting -Wstrict-prototypes in combination
with -Werror leads to compiler errors during
configure checks (autoconf generates incomplete
prototypes).

Adding -Wno-error=strict-prototypes lets the
compiler tolerate those.

Possible future enhancement: remember such
"configure time only" flags and remove them
from CFLAGS before generating our build time
files (Makefile, config_vars.mk etc.), so that
the full -Werror is in place during building.
