- Attempt to fix script compilation failure on versions older than 5.007003,
  corelist -a Time::HiRes lists this as the first version released with it.

- Ensure ftp check delay timer is always an integral number.

in cases like test 190

Slack time reduction

Added runtests.pl '-r' option for run time statistics

data is required in order to closer match total test execution time.

- In order to better reflect that the returned pid is extracted from the
  given file, serverpid sub is renamed to pidfromfile. In addition it is
  enhanced to make sure that it always returns zero unless a numerical
  positive value is returned.

- To better reflect that only process existance is actually checked,
  checkserver sub is renamed to processexists. In addition it is enhanced
  making it remove the given pid file when the extracted pid is no longer
  alive.

  each test, so that the test suite can now be used to actually test the
  verification of cert names etc. This made an error show up in the OpenSSL-
  specific code where it would attempt to match the CN field even if a
  subjectAltName exists that doesn't match. This is now fixed and verified
  in test 311.

renamed generated config.h to curl_config.h in order to avoid clashes when libcurl is used with other projects which also have a config.h.

With the curl memory tracking feature decoupled from the debug build feature,
CURLDEBUG and DEBUGBUILD preprocessor symbol definitions are used as follows:

CURLDEBUG used for curl debug memory tracking specific code (--enable-curldebug)

DEBUGBUILD used for debug enabled specific code (--enable-debug)

Extend displaying of logfiles upon first server start-up failure for http, https, ftp, ftps and tftp test harness servers.

The origin of the problem with test case #251 was the --ftp-port not being the CLIENTIP address.

David McCreedy's patch to fix test suite harness to allow test FTP server and client on different machines, providing FTP client address when running the FTP test server.

you use runtests.pl -g, will be sourced by gdb to allow additional fancy

when the tests stall.

  Re-enable all tests for debug-enabled builds.

  For debug-disabled builds only 8 tests are enabled.

return code.  This way, if the precheck command can't be run at all for
whatever reason, it's treated as a precheck failure which causes the
test to be skipped.

returns no other exitcode, use 2000 + signal number as return code
