docs/credential-store: s/--store/--file/

The option name "--store" was used early in development, but
never even made it into an applied patch, let alone a
released version of git. I forgot to update the matching
documentation at the time, though.

imap-send: use libcurl for implementation

Use libcurl's high-level API functions to implement git-imap-send
instead of the previous low-level OpenSSL-based functions.

Since version 7.30.0, libcurl's API has been able to communicate with
IMAP servers. Using those high-level functions instead of the current
ones would reduce imap-send.c by some 1200 lines of code. For now,
the old ones are wrapped in #ifdefs, and the new functions are enabled
by make if curl's version is >= 7.34.0, from which version on curl's
CURLOPT_LOGIN_OPTIONS (enabling IMAP authentication) parameter has been
available. The low-level functions will still be used for tunneling
into the server for now.

As I don't have access to that many IMAP servers, I haven't been able to
test the new code with a wide variety of parameter combinations. I did
test both secure and insecure (imaps:// and imap://) connections and
values of "PLAIN" and "LOGIN" for the authMethod.

DONTMERGE: minimum fixup
Documentation/git-commit: clarify that --only/--include records the working tree contents

With the original phrasing, it is possible to misunderstand as if
the contents in the index for only the specified paths are made into
the new commit.

Merge branch 'jc/clone-borrow' into jch

Allow "git clone --reference" to be used more safely.

* jc/clone-borrow:
  clone: --dissociate option to mark that reference is only temporary
Merge branch 'jc/checkout-local-track-report' into jch

The report from "git checkout" on a branch that builds on another
local branch by setting its branch.*.merge to branch name (not a
full refname) incorrectly said that the upstream is gone.

* jc/checkout-local-track-report:
  checkout: report upstream correctly even with loosely defined branch.*.merge
