The long list of architectures in include/curl/system.h is annoying to
maintain, and needs to be extended for each and every architecture to
support.
Instead, let's rely on the __SIZEOF_LONG__ define of the gcc compiler
(we are in the GNUC condition anyway), which tells us if long is 4
bytes or 8 bytes.
This fixes the build of libcurl 7.55.0 on architectures such as
OpenRISC or ARC.

Fixes the below leak:

Closes#1761
Visual Studio doesn't like LF line endings in solution files and always
converts them to CRLF when doing changes to the solution. Notably, this
affects the solutions in the release archive.
Closes https://github.com/curl/curl/pull/1746
The fix for this in 8661a0aacc01492e0436275ff36a21734f2541bb wasn't
complete: if the parsed number in num is larger than will fit in a long,
the conversion is undefined behaviour (causing test1427 to fail for me
on IA32 with GCC 7.1, although it passes on AMD64 and ARMv7). Getting
rid of the cast means the comparison will be done using doubles.
It might make more sense for the max argument to also be a double...
Fixes#1750Closes#1749
... since they now provide several functions as
__attribute__((overloadable)), the argument detection logic need
updates.

This updates the script to aad5ad5fedb306b39f901a899b7bd305b66c418d
from August 01, 2017. Notably, this removes the lconv version whitelist.
Closes https://github.com/curl/curl/pull/1716
Make the number parser aware of the maximum limit curl accepts for a
value and return an error immediately if larger, instead of running an
integer overflow later.
Fixes#1730Closes#1736
... and thereby avoid telling send() to send off more bytes than the
size of the buffer!
CVE-2017-1000100
Bug: https://curl.haxx.se/docs/adv_20170809B.html

First: this function is only used in debug-builds and not in
release/real builds. It is used to drive tests using the event-based
API.
A pointer to the local struct is passed to CURLMOPT_TIMERDATA, but the
CURLMOPT_TIMERFUNCTION calback can in fact be called even after this
funtion returns, namely when curl_multi_remove_handle() is called.
Reported-by: Brian Carpenter
When multiple rounds are needed to establish a security context
(usually ntlm), we overwrite old token with a new one without free.
Found by proposed gss tests using stub a gss implementation (by
valgrind error), though I have confirmed the leak with a real
gssapi implementation as well.
Closes https://github.com/curl/curl/pull/1733
