doh: allocate state struct on demand
... instead of having it static within the Curl_easy struct. This takes
away 1176 bytes (18%) from the Curl_easy struct that aren't used very
often and instead makes the code allocate it when needed.

socks: use the download buffer instead
The SOCKS code now uses the generic download buffer for temporary
storage during the connection procedure, instead of having its own
private 600 byte buffer that adds to the connectdata struct size. This
works fine because this point the buffer is allocated but is not use for
download yet since the connection hasn't completed.
This reduces the connection struct size by 22% on a 64bit arch!
The SOCKS buffer needs to be at least 600 bytes, and the download buffer
is guaranteed to never be smaller than 1000 bytes.

urldata: make magic be the first struct field
By making the `magic` identifier the same size and at the same place
within the structs (easy, multi, share), libcurl will be able to more
reliably detect and safely error out if an application passes in the
wrong handle to APIs. Easier to detect and less likely to cause crashes
if done.
Such mixups can't be detected at compile-time due to them being
typedefed void pointers - unless `CURL_STRICTER` is defined.

libssh: avoid plain free() of libssh-memory
Since curl's own memory debugging system redefines free() calls to track
and fiddle with memory, it cannot be used on memory allocated by 3rd
party libraries.
Third party libraries SHOULD NOT require free() to release allocated
resources for this reason - and libs can use separate healp allocators
on some systems (like Windows) so free() doesn't necessarily work
anyway.

lib: pass in 'struct Curl_easy *' to most functions
... in most cases instead of 'struct connectdata *' but in some cases in
addition to.
- We mostly operate on transfers and not connections.
- We need the transfer handle to log, store data and more. Everything in
libcurl is driven by a transfer (the CURL * in the public API).
- This work clarifies and separates the transfers from the connections
better.
- We should avoid "conn->data". Since individual connections can be used
by many transfers when multiplexing, making sure that conn->data
points to the current and correct transfer at all times is difficult
and has been notoriously error-prone over the years. The goal is to
ultimately remove the conn->data pointer for this reason.

gitattributes: Set batch files to CRLF line endings on checkout
If a batch file is run without CRLF line endings (ie LF-only) then
arbitrary behavior may occur. I consider that a bug in Windows, however
the effects can be serious enough (eg unintended code executed) that
we're fixing it in the repo by requiring CRLF line endings for batch
files on checkout.
Prior to this change the checked-out line endings of batch files were
dependent on a user's git preferences. On Windows it is common for git
users to have automatic CRLF conversion enabled (core.autocrlf true),
but those users that don't would run into this behavior.
For example a user has reported running the Visual Studio project
generator batch file (projects/generate.bat) and it looped forever.
Output showed that the Windows OS interpreter was occasionally jumping
to arbitrary points in the batch file and executing commands. This
resulted in unintended files being removed (a removal sequence called)
and looping forever.

tool_doswin: Restore original console settings on CTRL signal
- Move Windows terminal init code from tool_main to tool_doswin.
- Restore the original console settings on CTRL+C and CTRL+BREAK.
Background: On Windows the curl tool changes the console settings to
enable virtual terminal processing (eg color output) if supported
(ie Win 10). The original settings are restored on exit but prior to
this change were not restored in the case of the CTRL signals.
Windows VT behavior varies depending on console/powershell/terminal;
refer to the discussion in #6226.

docs: fix line length bug in gen.pl
The script warns if the length of $opt and $desc is > 78. However, these

Also the $bitmask field is totally forgotten. Currently this leads to
two warnings within `--resolve` and `--aws-sigv4`.

data could be read in and ignored (since this is what we do with any
CONNECT response body) and the connection could not be used.
