When reloading the configuration with :reload, global variables in the
config package are reset to their startup values and then, the config is
parsed from disk. While the parsing is done, these variables are
temporarily in an inconsistent and possibly invalid state.
When commands are executed interactively from aerc, they are handled by
the main goroutine which also deals with UI rendering. No UI render will
be done while :reload is in progress.
However, the IPC socket handler runs in an independent goroutine. This
has the unfortunate side effect to let the UI goroutine to run while
config parsing is in progress and causes crashes:
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x6bb142]

Make the reload operation safe by changing how config objects are
exposed and updated. Change all objects to be atomic pointers. Expose
public functions to access their value atomically. Only update their
value after a complete and successful config parse. This way the UI
thread will always have access to a valid configuration.
NB: The account configuration is not included in this change since it
cannot be reloaded.

So far, the :tag command in the notmuch and jmap workers allows adding a
tag (by prefixing it with '+') and removing it (by prefixing it with
'-'). Add a new functionality to this command, allowing it to toggle a
tag by prefixing it with '!'.
Fixes: https://todo.sr.ht/~rjarry/aerc/292
Changelog-added: It is now possible to toggle notmuch and JMAP tags.

Currently the only feedback we have from hooks is the error code. Log
STDOUT on loglevel TRACE and log STDERR on loglevel ERROR if the command
exists with an error.

It can be good to know the backend used for an account in a hook. Add
this information to all hooks that already pass the account name along.
Changelog-added: Added `AERC_ACCOUNT_BACKEND` to hooks with
`AERC_ACCOUNT`.

It's logical to pass this information as well, when we pass a folder

`AERC_FOLDER`.

When scripting for the mail-received hook, it can be useful to identify
a mail in a maildir. In that case the Message-ID might be one of the
most useful parameters to go for identifying the file of a message.
Changelog-changed: Add Message-ID to the variables of
`[hooks].mail-received`.

The mail-added hook runs whenever a message is added to a folder.
Note that the hook does not run when a new message is received (the
mail-received hook already covers that) but instead runs whenever aerc
itself adds a message to a folder, e.g. when moving or copying a
message.
Changelog-added: `mail-added` hook that triggers when a message is added
to a folder.

The mail-deleted hook runs whenever a message is deleted from a folder.
Note that this means moving a message from one folder to another
triggers the mail-deleted hook.

removed/moved from a folder.

Deprecate triggers and replace them with hooks. Now that aerc supports
running arbitrary ex commands over IPC, it is possible to run internal
aerc commands *and* shell commands via external shell scripts. Hooks
only allow running shell commands. Hooks info is passed via environment
variables.
