error: conversion to 'long int' from 'time_t {aka long long int}' may alter
its value [-Werror=conversion]

If Makefile.am uses CRLF, buildconf in a Windows checkout fails with:
".ibtoolize: error: AC_CONFIG_MACRO_DIRS([m4]) conflicts with
ACLOCAL_AMFLAGS=-I m4"

Added test 1442 to verify

curl must be built before building the tests.

Closes https://github.com/curl/curl/pull/1352

Send curl_socket_t to event_cb and make sure it hasn't been closed yet.

Closes https://github.com/curl/curl/pull/1318

- If SSL_get_error is called but no extended error detail is available
  then show that SSL_ERROR_* as a string.

Prior to this change there was some inconsistency in that case: the
SSL_ERROR_* code may or may not have been shown, or may have been shown
as unknown even if it was known.

Running this in the root build dir will invoke the test suite to only
run tests not marked as 'flaky'.

Note that for some reason there is this warning (that also exists with
autotools, added since curl-7_15_1-94-ga718cb05f):

    docs/libcurl/curl_multi_socket_all.3:1: can't open `man3/curl_multi_socket.3': No such file or directory

Additionally, adjust the roffit --mandir option to support creating
links when doing out-of-tree builds.

Also make Perl mandatory to allow building the docs.

While CMakeLists.txt could probably read the list of manual pages from
Makefile.am, actually putting those in CMakeLists.txt is cleaner so that
is what is done here.

Fixes #1230

For easier sharing with CMake. The contents were reformatted to use
two-space indent and expanded tabs (matching lib/Makefile.common).

Ref: https://github.com/curl/curl/pull/1288

The code would refer to the wrong data pointer. Only debug builds do
this - for verbosity.

Fixes #1329

These tests use an HTTP proxy so require that curl be built with HTTP
support.

The CURLOPT_USERAGENT and CURLOPT_MAXREDIRS options are only set if HTTP
support is available, so ignore them in tests where HTTP is not
guaranteed.

Broken a week ago in 6448f98c.

Closes https://github.com/curl/curl/pull/1337

- Show the HTTPS-proxy options on CURLE_SSL_CACERT if libcurl was built
  with HTTPS-proxy support.

Prior to this change those options were shown only if an HTTPS-proxy was
specified by --proxy, but that did not take into account environment
variables such as http_proxy, https_proxy, etc. Follow-up to e1187c42.
