The stub implementation is pre-loaded using LD_PRELOAD
and emulates common gssapi uses (only builds if curl is
initially built with gssapi support).
The initial tests are currently disabled for debug builds
as LD_PRELOAD is not used then.

- Prepend srcdir include path instead of append.
Prior to this change it was possible that during the check for the size
of curl_off_t the include path of a user's already installed curl could
come before the include path of the to-be-built curl, resulting in the
system.h of the former being incorrectly included for that check.
Closes https://github.com/curl/curl/pull/1870
Back in 2008, (and commit 3f3d6ebe66) we changed the logic in how we
determine the native type for `curl_off_t`. To really make sure we
didn't break ABI without bumping SONAME, we introduced logic that
attempted to detect that it would use a different size and thus not be
compatible. We also provided a manual switch that allowed users to tell
configure to bump SONAME by force.
Today, we know of no one who ever got a SONAME bump auto-detected and we
don't know of anyone who's using the manual bump feature. The auto-
detection is also no longer working since we introduced defining
curl_off_t in system.h (7.55.0).
Finally, this bumping logic is not present in the cmake build.
Closes#1861
Automake gets confused if you want to use C++ static libraries with C
code - basically we need to involve the clang++ linker. The easiest way
of achieving this is to rename the C code as C++ code. This gets us a
bit further along the path and ought to be compatible with Google's
version of clang.
- Start with the basic code from the ossfuzz project.
- Rewrite fuzz corpora to be binary files full of Type-Length-Value
data, and write a glue layer in the fuzzing function to convert
corpora into CURL options.
- Have supporting functions to generate corpora from existing tests
- Integrate with Makefile.am
There is a mode in which libcurl is compiled with versioned symbols,
depending on the active SSL backend.
When multiple SSL backends are active, it does not make sense to favor
one over the others, so let's not: introduce a new prefix for the case
where multiple SSL backends are compiled into cURL.

Previously, we used as default SSL backend whatever was first in the
`available_backends` array.
However, some users may want to override that default without patching
the source code.
Now they can: with the --with-default-ssl-backend=<backend> option of
the ./configure script.

When building software for the masses, it is sometimes not possible to
decide for all users which SSL backend is appropriate.
Git for Windows, for example, uses cURL to perform clones, fetches and
pushes via HTTPS, and some users strongly prefer OpenSSL, while other
users really need to use Secure Channel because it offers
enterprise-ready tools to manage credentials via Windows' Credential
Store.
The current Git for Windows versions use the ugly work-around of
building libcurl once with OpenSSL support and once with Secure Channel
support, and switching out the binaries in the installer depending on
the user's choice.
Needless to say, this is a super ugly workaround that actually only
works in some cases: Git for Windows also comes in a portable form, and
in a form intended for third-party applications requiring Git
functionality, in which cases this "swap out libcurl-4.dll" simply is
not an option.
Therefore, the Git for Windows project has a vested interest in teaching
cURL to make the SSL backend a *runtime* option.
This patch makes that possible.
By running ./configure with multiple --with-<backend> options, cURL will
be built with multiple backends.
For the moment, the backend can be configured using the environment
variable CURL_SSL_BACKEND (valid values are e.g. "openssl" and
"schannel").

This change does two things:
1. It un-breaks the build in Xcode 9.0. (Xcode 9.0 is currently
failing trying to compile connectx() in lib/connect.c.)
2. It finally weak-links the connectx() function, and falls back on
connect() when run on older operating systems.
- Change prepends to appends because user's LDFLAGS and CPPFLAGS should
always come first so they're searched before ours.

The check for if -ldl is needed to build with (a statically built)
openssl was broken. This repairs the check, and adds a check for
-lpthread as well since OpenSSL 1.1.0+ does in fact require -lpthread so
only adding -ldl for a static openssl build is no longer enough.

Prior to this change if you attempted to configure curl using
--wtih-zlib and specified a path the path would be ignored if you also
had pkg-config installed on your system. This situation can easily
arise when you are cross compiling. This change moves the test for
detecting zlib settings via pkg-config only if OPT_ZLIB is not set.
Closes https://github.com/curl/curl/pull/1292
When the threaded resolver option is specified for configure the default
thread library is pthreads. This change makes it possible to
--disable-pthreads and then configure can fall back on Win32 threads for
native Windows builds.

Check for presence of gnutls_alpn_* and gnutls_ocsp_* functions during
configure instead of relying on the version number. GnuTLS has options
to turn these features off and we ca just work with with such builds
like we work with older versions.

The OpenSSL function CRYTPO_cleanup_all_ex_data() cannot be called
multiple times without crashing - and other libs might call it! We
basically cannot call it without risking a crash. The function is a
no-op since OpenSSL 1.1.0.
Not calling this function only risks a small memory leak with OpenSSL <
1.1.0.

Since I first wrote that text, Apple introduced tvOS and watchOS, and renamed "Mac OS X" to "macOS." Let's make the text a little more inclusive, since curl can be built for all four operating systems.
With commit c2f9b78 we added a new dependency on pkg-config for
developers which may be unwanted. This change make the configure script
still work as before if pkg-config isn't installed, it'll just use the
old zlib detection logic without pkg-config.
