be a 64-bit integer. This is the case when building for recent macOS

Background:
148534d added CURLSSLOPT_NATIVE_CA to use the Windows OS certificate
store in libcurl w/ OpenSSL on Windows. CURLSSLOPT_NATIVE_CA overrides
CURLOPT_CAINFO if both are set. The curl tool will fall back to
CURLSSLOPT_NATIVE_CA if it could not find a certificate bundle to set
via CURLOPT_CAINFO.
Problem:
libcurl may be built with hardcoded paths to a certificate bundle or
directory, and if CURLSSLOPT_NATIVE_CA is used then those paths are
ignored.
Solution:
A solution is still being discussed but since there's an impending
release this commit removes using CURLSSLOPT_NATIVE_CA in the curl tool.

- Implement new option CURLSSLOPT_REVOKE_BEST_EFFORT and
--ssl-revoke-best-effort to allow a "best effort" revocation check.
A best effort revocation check ignores errors that the revocation check
was unable to take place. The reasoning is described in detail below and
discussed further in the PR.
---
When running e.g. with Fiddler, the schannel backend fails with an
unhelpful error message:
Unknown error (0x80092012) - The revocation function was unable
to check revocation for the certificate.
Sadly, many enterprise users who are stuck behind MITM proxies suffer
the very same problem.
This has been discussed in plenty of issues:
https://github.com/curl/curl/issues/3727,
https://github.com/curl/curl/issues/264, for example.
In the latter, a Microsoft Edge developer even made the case that the
common behavior is to ignore issues when a certificate has no recorded
distribution point for revocation lists, or when the server is offline.
This is also known as "best effort" strategy and addresses the Fiddler
issue.
Unfortunately, this strategy was not chosen as the default for schannel
(and is therefore a backend-specific behavior: OpenSSL seems to happily
ignore the offline servers and missing distribution points).
To maintain backward-compatibility, we therefore add a new flag
(`CURLSSLOPT_REVOKE_BEST_EFFORT`) and a new option
(`--ssl-revoke-best-effort`) to select the new behavior.
Due to the many related issues Git for Windows and GitHub Desktop, the
plan is to make this behavior the default in these software packages.
The test 2070 was added to verify this behavior, adapted from 310.

- Change tool_util.c tvnow() for Windows to match more closely to
timeval.c Curl_now().
- Create a win32 init function for the tool, since some initialization
is required for the tvnow() changes.
Prior to this change the monotonic time function used by curl in Windows
was determined at build-time and not runtime. That was a problem because
when curl was built targeted for compatibility with old versions of
Windows (eg _WIN32_WINNT < 0x0600) it would use GetTickCount which wraps
every 49.7 days that Windows has been running.
This change makes curl behave similar to libcurl's tvnow function, which
determines at runtime whether the OS is Vista+ and if so calls
QueryPerformanceCounter instead. (Note QueryPerformanceCounter is used
because it has higher resolution than the more obvious candidate
GetTickCount64). The changes to tvnow are basically a copy and paste but
the types in some cases are different.

- Deduplicate GetEnv() code.
- On Windows change ultimate call to use Windows API

Prior to this change both libcurl and the tool had their own GetEnv
which over time diverged. Now the tool's GetEnv is a wrapper around
curl_getenv (libcurl API function which is itself a wrapper around
libcurl's GetEnv).
Furthermore this change fixes a bug in that Windows API
GetEnvironmentVariable() is called instead of C runtime getenv() to get
the environment variable since some changes aren't always visible to the
latter.

Some file systems allow for directory traversal; in this case that it

This is a regression caused by me in f16bed0 (precedes curl-7_61_1).
Basically I had assumed that if a directory already existed it would
fail only with error EEXIST, and not error EACCES. The latter may
happen if the directory exists but has certain restricted permissions.

- Disable warning C4127 "conditional expression is constant" globally
in curl_setup.h for when building with Microsoft's compiler.
This mainly affects building with the Visual Studio project files found
in the projects dir.
Prior to this change the cmake and winbuild build systems already
disabled 4127 globally for when building with Microsoft's compiler.
Also, 4127 was already disabled for all build systems in the limited
circumstance of the WHILE_FALSE macro which disabled the warning
specifically for while(0). This commit removes the WHILE_FALSE macro and
all other cruft in favor of disabling globally in curl_setup.
Background:
We have various macros that cause 0 or 1 to be evaluated, which would
cause warning C4127 in Visual Studio. For example this causes it:
#define Curl_resolver_asynch() 1
Full behavior is not clearly defined and inconsistent across versions.
However it is documented that since VS 2015 Update 3 Microsoft has
addressed this somewhat but not entirely, not warning on while(true) for
example.
Prior to this change some C4127 warnings occurred when I built with
Visual Studio using the generated projects in the projects dir.

Starting with this change when doing parallel transfers, without this

--parallel-immediate can be set to tell curl to prefer to use new

Even though it cannot fall-back to a lower HTTP version automatically. The

Closes#4197
Repeatedly we see problems where using curl_multi_wait() is difficult or
just awkward because if it has no file descriptor to wait for
internally, it returns immediately and leaves it to the caller to wait
for a small amount of time in order to avoid occasional busy-looping.
This is often missed or misunderstood, leading to underperforming
applications.
This change introduces curl_multi_poll() as a replacement drop-in
function that accepts the exact same set of arguments. This function
works identically to curl_multi_wait() - EXCEPT - for the case when
there's nothing to wait for internally, as then this function will by
itself wait for a "suitable" short time before it returns. This
effectiely avoids all risks of busy-looping and should also make it less
likely that apps "over-wait".
This also changes the curl tool to use this funtion internally when
doing parallel transfers and changes curl_easy_perform() to use it
internally.
