- the expression of an 'if' was always true
- a 'while' contained a condition that was always true
- use 'if(k->exp100 > EXP100_SEND_DATA)' instead of 'if(k->exp100)'
- fixed a typo

Closes #889

... as otherwise we could get a 0 which would count as no error and we'd
wrongly continue and could end up segfaulting.

... as previously the README.cmake would be picked and put at the bottom
of the docs page there and it wasn't very representative!

The FreeBSD Port security/ca_root_nss installs the Mozilla NSS CA bundle
to /usr/local/share/certs/ca-root-nss.crt. Use this bundle in the
discovery process.

This change also removes the former FreeBSD path that has been obsolete
for 8 years since this FreeBSD ports commit:
https://svnweb.freebsd.org/ports/head/security/?view=revision&revision=215953

Closes #894

Another follow up for crypt32.lib linking with winssl

Fixes #853

Closes #854

Broken since 6cabd785, which adds use of the Curl_extract_certinfo
function from the x509asn1.c file.

... and save the typedef'ed names for headers and external APIs.

Instead of typedef'ing to void, typedef to their corresponding actual
struct names to allow compilers to type-check.

Prior to this change we called Curl_ssl_getsessionid and
Curl_ssl_addsessionid regardless of whether session ID reusing was
enabled. According to comments that is in case session ID reuse was
disabled but then later enabled.

The old way was not intuitive and probably not something users expected.
When a user disables session ID caching I'd guess they don't expect the
session ID to be cached anyway in case the caching is later enabled.

Closes #883

CMake build now using BUILD_TESTING=ON/OFF (default is OFF) to build
tests and enabling CTest integration. Options BUILD_CURL_TESTS and
BUILD_DASHBOARD_REPORTS was removed.

Closes #887

Some builds of GCC produce output on both stdout and stderr when --help
--verbose is used.  The 2>&1 redirection caused them to be arbitrarily
interleaved with each other because of stream buffering.  Consequently,
grep failed to match the fvisibility= string in the mixed output, even
though the string was present in GCC's standard output.

This led to silently disabling symbol hiding in some builds of curl.

The HTTP/2 tests brought with commit bf05606e were using the internal
name 'http2' for the HTTP/2 server, while in fact that name was already
used for the second instance of the HTTP server. This made tests using
the second instance (like test 2050) fail after a HTTP/2 test had run.

The server is now known as HTTP/2 internally and within the <server>
section in test cases. 1700, 1701 and 1702 were updated accordingly.
