Bernhard Reiter 1e16b255b9 git-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.

In order to suppress a sparse warning about "using sizeof on a
function", we use the same solution used in commit 9371322a6
("sparse: suppress some "using sizeof on a function" warnings",
06-10-2013) which solved exactly this problem for the other commands
using libcurl.

NAME
----
git-imap-send - Send a collection of patches from stdin to an IMAP folder
SYNOPSIS
--------
[verse]
'git imap-send' [-v] [-q] [--[no-]curl]
DESCRIPTION
-----------
This command uploads a mailbox generated with 'git format-patch'
into an IMAP drafts folder. This allows patches to be sent as
other email is when using mail clients that cannot read mailbox
files directly. The command also works with any general mailbox
in which emails have the fields "From", "Date", and "Subject" in
that order.
Typical usage is something like:
git format-patch --signoff --stdout --attach origin | git imap-send
OPTIONS
-------
-v::
--verbose::
Be verbose.
-q::
--quiet::
Be quiet.
--curl::
Use libcurl to communicate with the IMAP server, unless tunneling
into it. Ignored if Git was built without the USE_CURL_FOR_IMAP_SEND
option set.
--no-curl::
Talk to the IMAP server using git's own IMAP routines instead of
using libcurl.
CONFIGURATION
-------------
To use the tool, imap.folder and either imap.tunnel or imap.host must be set
to appropriate values.
Variables
~~~~~~~~~
imap.folder::
The folder to drop the mails into, which is typically the Drafts
folder. For example: "INBOX.Drafts", "INBOX/Drafts" or
"[Gmail]/Drafts". Required.
imap.tunnel::
Command used to setup a tunnel to the IMAP server through which
commands will be piped instead of using a direct network connection
to the server. Required when imap.host is not set.
imap.host::
A URL identifying the server. Use a `imap://` prefix for non-secure
connections and a `imaps://` prefix for secure connections.
Ignored when imap.tunnel is set, but required otherwise.
imap.user::
The username to use when logging in to the server.
imap.pass::
The password to use when logging in to the server.
imap.port::
An integer port number to connect to on the server.
Defaults to 143 for imap:// hosts and 993 for imaps:// hosts.
Ignored when imap.tunnel is set.
imap.sslverify::
A boolean to enable/disable verification of the server certificate
used by the SSL/TLS connection. Default is `true`. Ignored when
imap.tunnel is set.
imap.preformattedHTML::
A boolean to enable/disable the use of html encoding when sending
a patch. An html encoded patch will be bracketed with <pre>
and have a content type of text/html. Ironically, enabling this
option causes Thunderbird to send the patch as a plain/text,
format=fixed email. Default is `false`.
imap.authMethod::
Specify authenticate method for authentication with IMAP server.
If Git was built with the NO_CURL option, or if your curl version is older
than 7.34.0, or if you're running git-imap-send with the `--no-curl`
option, the only supported method is 'CRAM-MD5'. If this is not set
then 'git imap-send' uses the basic IMAP plaintext LOGIN command.
Examples
~~~~~~~~
Using tunnel mode:
..........................
[imap]
folder = "INBOX.Drafts"
tunnel = "ssh -q -C user@example.com /usr/bin/imapd ./Maildir 2> /dev/null"
..........................
Using direct mode:
.........................
[imap]
folder = "INBOX.Drafts"
host = imap://imap.example.com
user = bob
pass = p4ssw0rd
.........................
Using direct mode with SSL:
.........................
[imap]
folder = "INBOX.Drafts"
host = imaps://imap.example.com
user = bob
pass = p4ssw0rd
port = 123
sslverify = false
.........................
EXAMPLE
-------
To submit patches using GMail's IMAP interface, first, edit your ~/.gitconfig
to specify your account settings:
---------
[imap]
folder = "[Gmail]/Drafts"
host = imaps://imap.gmail.com
user = user@gmail.com
port = 993
sslverify = false
---------
You might need to instead use: folder = "[Google Mail]/Drafts" if you get an error
that the "Folder doesn't exist".
Once the commits are ready to be sent, run the following command:
$ git format-patch --cover-letter -M --stdout origin/master | git imap-send
Just make sure to disable line wrapping in the email client (GMail's web
interface will wrap lines no matter what, so you need to use a real
IMAP client).
CAUTION
-------
It is still your responsibility to make sure that the email message
sent by your email program meets the standards of your project.
Many projects do not like patches to be attached. Some mail
agents will transform patches (e.g. wrap lines, send them as
format=flowed) in ways that make them fail. You will get angry
flames ridiculing you if you don't check this.
Thunderbird in particular is known to be problematic. Thunderbird
