Properly use libtool macros to fix OpenLDAP library name detection on Darwin.

add debug messages for initialization failures

when using select() instead of poll, skip the test if the number of
open file descriptors is greater than FD_SETSIZE minus SAFETY_MARGIN,
also skip the test if any of the open file descriptor

fix temp string buffer variable name

Support for OpenWatcom (Win32): It do have getpid(), but no
<sys/time.h>.

start working on 7.16.2

skip test on platforms on which we use select() instead
of poll() and select() happens to be bound by FD_SETSIZE

fix compiler warning "discards qualifiers from pointer target type" in debug builds

the same source file is re-used for multiple tests and I missed to add the
timval.c dependency on some of those

Some compilers lacks <sys/time.h>. Include "timeval.h" to simplify the #ifdefs.

Use DOS line-endings.

release time

the user-agent fix

the libtest source codes that use curlx_tv* functions MUST use the
lib/timeval.c source code since those functions are not in the API (and might
not be accessible)

- Michael Wallner reported that when doing a CONNECT with a custom User-Agent
header, you got _two_ User-Agent headers in the CONNECT request...! Added
test case 287 to verify the fix.

fixed segfault when compiled with MingW32 and cmd or command shell.

Andreas Rieke added extra infof() for when a connection is not re-used due to
SSL conditions not being the same

silence compiler warnings

enabled build with sspi.

enabled build with hardcoded ca-bundle path;
added distclean target.

force to create ca-bunde.h even if it exists already.

use var for awk.

curl_easy_reset() now resets the CA bundle path correctly

another small fix to directory listing output; disabled CURL_LIBSSH2_DEBUG.
