write-out.d: clarify Windows % symbol escaping
- Clarify that in Windows batch files the % must be escaped as %%, and
at the command prompt it cannot be escaped which could lead to
incorrect expansion.
Prior to this change the doc implied % must be escaped as %% in win32
always.
---
Examples showing how a write-out argument is received by curl:
If curl --write-out "%{http_code}" is executed in a batch file:
{http_code}
If curl --write-out "%%{http_code}" is executed in a batch file:
%{http_code}
If curl --write-out "%{http_code}" is executed from the command prompt:
%{http_code}
If curl --write-out "%%{http_code}" is executed from the command prompt:
%%{http_code}
At the command prompt something like "%{speed_download}%{http_code}"
would first be parsed by the command interpreter as %{speed_download}%
and would be expanded as environment variable {speed_download} if it
existed, though that's highly unlikely since Windows environment names
don't use braces.

CURLOPT_HEADERDATA.3: warn DLL users must set write function
- Warn that in Windows if libcurl is running from a DLL and if
CURLOPT_HEADERDATA is set then CURLOPT_WRITEFUNCTION or
CURLOPT_HEADERFUNCTION must be set as well, otherwise the user may
experience crashes.
We already have a similar warning in CURLOPT_WRITEDATA. Basically, in
Windows libcurl could crash writing a FILE pointer that was created by
a different C runtime. In Windows each DLL that is part of a program may
or may not have its own C runtime.
Built-in TLS backends are detected at test time by scanning for their
names in the version string line returned by the cli tool: as this line
may also list the libssh configuration that mentions its own backend,
the curl backend may be wrongly determined.
In example, if the version line contains "libssh/0.10.4/openssl/zlib",
OpenSSL is detected as a curl-configured backend even if not.
This fix requires the backend names to appear as full words preceded by
spacing in the version line to be recognized as curl TLS backends.
