urlapi: provide more detailed return codes
Previously, the return code CURLUE_MALFORMED_INPUT was used for almost
30 different URL format violations. This made it hard for users to
understand why a particular URL was not acceptable. Since the API cannot
point out a specific position within the URL for the problem, this now
instead introduces a number of additional and more fine-grained error
codes to allow the API to return more exactly in what "part" or section
of the URL a problem was detected.

Also bug-fixes curl_url_get() with CURLUPART_ZONEID, which previously
returned CURLUE_OK even if no zoneid existed.

Test cases in 1560 have been adjusted and extended. Tests 1538 and 1559
have been updated.

Updated libcurl-errors.3 and curl_url_strerror() accordingly.

b0eda8dc6e strerror: use sys_errlist instead of strerror on Windows
- Change Curl_strerror to use sys_errlist[errnum] instead of strerror to
  retrieve the error message on Windows.

Windows' strerror writes to a static buffer and is not thread-safe.

Follow-up to 2f0bb86 which removed most instances of strerror in favor
of calling Curl_strerror (which calls strerror_r for other platforms).

strerror: Revert to local codepage for Windows error string
- Change get_winapi_error() to return the error string in the local
  codepage instead of UTF-8 encoding.

Two weeks ago bed5f84 fixed get_winapi_error() to work on xbox, but it
also changed the error string's encoding from local codepage to UTF-8.

We return the local codepage version of the error string because if it
is output to the user's terminal it will likely be with functions which
expect the local codepage (eg fprintf, failf, infof).

This is essentially a partial revert of bed5f84. The support for xbox
remains but the error string is reverted back to local codepage.

CURLE_PROXY: new error code
Failures clearly returned from a (SOCKS) proxy now causes this return
code. Previously the situation was not very clear as what would be
returned and when.

In addition: when this error code is returned, an application can use
CURLINFO_PROXY_ERROR to query libcurl for the detailed error, which then
returns a value from the new 'CURLproxycode' enum.

5b22e1a5a9 strerror: Add Curl_winapi_strerror for Win API specific errors
- In all code call Curl_winapi_strerror instead of Curl_strerror when
  the error code is known to be from Windows GetLastError.

Curl_strerror prefers CRT error codes (errno) over Windows API error
codes (GetLastError) when the two overlap. When we know the error code
is from GetLastError it is more accurate to prefer the Windows API error
messages.

07cf042ece strerror: Fix an error looking up some Windows error strings
- Use FORMAT_MESSAGE_IGNORE_INSERTS to ignore format specifiers in
  Windows error strings.

Since we are not in control of the error code we don't know what
information may be needed by the error string's format specifiers.

Prior to this change Windows API error strings which contain specifiers
(think specifiers like similar to printf specifiers) would not be shown.
The FormatMessage Windows API call which turns a Windows error code into
a string could fail and set error ERROR_INVALID_PARAMETER if that error
string contained a format specifier. FormatMessage expects a va_list for
the specifiers, unless inserts are ignored in which case no substitution
is attempted.

strerror: make the strerror function use local buffers
Instead of using a fixed 256 byte buffer in the connectdata struct.

In my build, this reduces the size of the connectdata struct by 11.8%,
from 2160 to 1904 bytes with no functionality or performance loss.

This also fixes a bug in schannel's Curl_verify_certificate where it
called Curl_sspi_strerror when it should have called Curl_strerror for
string from GetLastError. the only effect would have been no text or the
wrong text being shown for the error.

To avoid that they cause problems with system includes, we include
curl_printf.h after any system headers. That makes the three last
headers to always be, and we keep them in this order:

 curl_printf.h
 curl_memory.h
 memdebug.h

None of them include system headers, they all do funny #defines.
