If a call to GetSystemDirectory fails, the `path` pointer that was
previously allocated would be leaked. This makes sure that `path` is
always freed.
Closes#938
This is a follow up to the parent commit dcdd4be which fixes one leak
but creates another by failing to free the credentials handle if out of
memory. Also there's a second location a few lines down where we fail to
do same. This commit fixes both of those issues.
- 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.

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.
- Enable protocol family logic for IPv6 resolves even when support
for synthesized addresses is enabled.
This is a follow up to the parent commit that added support for
synthesized IPv6 addresses from IPv4 on iOS/OS X. The protocol family
logic needed for IPv6 was inadvertently excluded if support for
synthesized addresses was enabled.

Use getaddrinfo() to resolve the IPv4 address literal on iOS/Mac OS X.
If the current network interface doesn’t support IPv4, but supports
IPv6, NAT64, and DNS64.

Calling QueryContextAttributes with SECPKG_ATTR_APPLICATION_PROTOCOL
fails on Windows < 8.1 so we need to disable ALPN on these OS versions.

- Change the parser to not require a minor version for HTTP/2.
HTTP/2 connection reuse broke when we changed from HTTP/2.0 to HTTP/2
in 8243a95 because the parser still expected a minor version.

Sessionid cache management is inseparable from managing individual
session lifetimes. E.g. for reference-counted sessions (like those in
SChannel and OpenSSL engines) every session addition and removal
should be accompanied with refcount increment and decrement
respectively. Failing to do so synchronously leads to a race condition
that causes symptoms like use-after-free and memory corruption.
This commit:
- makes existing session cache locking explicit, thus allowing
individual engines to manage lock's scope.
- fixes OpenSSL and SChannel engines by putting refcount management
inside this lock's scope in relevant places.
- adds these explicit locking calls to other engines that use
sessionid cache to accommodate for this change. Note, however,
that it is unknown whether any of these engines could also have
this race.

Mostly in order to support broken web sites that redirect to broken URLs
that are accepted by browsers.
Browsers are typically even more leniant than this as the WHATWG URL
spec they should allow an _infinite_ amount. I tested 8000 slashes with
Firefox and it just worked.
Added test case 1141, 1142 and 1143 to verify the new parser.
Closes#791
Regression from the previous *printf() rearrangements, this file missed to
include the correct header to make sure snprintf() works universally.
