Closes #1770

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.

Closes #1766

Suspicion: when we enabled the threaded resolver by default.

Fixes the below leak:

Closes #1761

A gcc7 warning.

Just making the pointer as const works for the pre-1.1.0 path too.

Closes #1759

To avoid "old crap" unintentionally getting shipped.

Closes #1753

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/1742

These weren't included in the 7.55.0 release, but are required in order
to run the full test suite.

Closes #1744

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...
