Reported-By: Henry Roeland

Some servers return a "content-encoding" header with a non-standard
"none" value.

Add "none" as an alias to "identity" as a work-around, to avoid
unrecognised content encoding type errors.

Windows 10.0.17061 SDK introduces support for Unix Domain Sockets.
Added the necessary include file to curl_addrinfo.c.

Note: The SDK (which is considered beta) has to be installed, VS 2017
project file has to be re-targeted for Windows 10.0.17061 and #define
enabled in config-win32.h.

Whilst the compiler parameter is mandatory, platform is optional as it
is automatically calculated by the :configure section.

This partially reverts commit 6d62d2c5.

When peer verification is disabled, calling
SSL_CTX_load_verify_locations is not necessary. Only call it when
verification is enabled to save resources and increase performance.

...and not just the Community Edition.

On Windows, stat() may adjust the unix file time by a daylight saving time
offset. Avoid this by calling GetFileTime() instead.

Reduce code duplication by making Curl_mime_contenttype available and
used by the formdata function. This also makes the formdata function
recognize a set of more file extensions by default.

PR #2280 brought this to my attention.

Closes #2282

...as that's how the function is documented to work.

Whenever an expected pattern syntax rule cannot be matched, the
character starting the rule loses its special meaning and the parsing
is resumed:
- backslash at the end of pattern string matches itself.
- Error in [:keyword:] results in set containing :\[dekorwy.

Unit test 1307 updated for this new situation.

Closes #2273

Also be more tolerant about set pattern syntax.
Update unit test 1307 accordingly.

To verify a proxy's public key. For when using HTTPS proxies.

Closes #2268

The logic tries to figure out what the path separator in the $PATH
variable is, but if there's only one directory in the $PATH it
fails. This change make configure *guess* on colon instead of erroring
out, simply because that is probably the more common character.

PATH_SEPARATOR can always be set by the user to override the guessing.

(tricky bug to reproduce, as in my case for example the configure script
requires binaries in more than one directory so passing in a PATH with a
single dir fails.)

... since the libc provided one are locale dependent in a way we don't
want. Also, the "native" isalnum() (for example) works differently on
different platforms which caused test 1307 failures on macos only.
