commands/account: Disable :view for deleted msgs

Allowing the user to view deleted messages creates all sorts of race
conditions. The most devious race condition is pv.source can be set to a
nil while another PartViewer is still running a goroutine in
attemptCopy.

Here is a trace when this happens.

goroutine 76 [running]: io.copyBuffer(0x7f8ad02641d0, 0xc00040f590, 0x0,
0x0, 0xc0007cc000, 0x8000, 0x8000, 0x0, 0x0, 0x8b3d60)
/usr/lib/go/src/io/io.go:402 +0x101 io.Copy(...)
/usr/lib/go/src/io/io.go:364
git.sr.ht/~sircmpwn/aerc/widgets.(*PartViewer).attemptCopy.func4(0xc00017efd0,
0xc0004da7c0) /home/keur/repos/aerc/widgets/msgviewer.go:576 +0x611
created by git.sr.ht/~sircmpwn/aerc/widgets.(*PartViewer).attemptCopy
/home/keur/repos/aerc/widgets/msgviewer.go:544 +0x144

We could add a guard in store.FetchBodyPart to only call the callback
when msg.Part.Reader != nil, but we still get a hanging pager. Therefore
it seems more reasonable to disable this completely.

Complete the F rune.

%F now shows the auth name or recepient name/address if the
message is from you.
Add UI options to save/pipe messages with unsupported mimetypes

Adds a message indicating the user's ability to :save or :pipe a message
with an unsupported mimetype and also adds a selector widget (similar to
the tutorial).

The selector widget was previously defined in the account wizard module,
so this commit breaks it out into its own module to allow for re-use.

Further, modify the BeginExLine() function to take an argument that
pre-populates the command line, allowing functions to initiate an ex
command without executing it.

Closes #95.
Check for terminal before forwarding mouse event

When viewing a message part with no available filter, clicking the UI
would cause a nil pointer dereference because the MouseEvent was passed
to the PartViewer's `term` field, which does not exist in the case of an
absent filter.
worker/imap: Fix seqMap race condition

When deleting a message, sometimes FetchDirectoryContents will fire.
FetchDirectoryContents will return a smaller set of UIDs since messages
have been deleted. This operation races with fetching from the seqMap in
client.ExpungeUpdate. Only recreate the seqMap if it can grow so that
messages will continue to be expunged.

Add support for AUTH LOGIN submission

`go-sasl` upstream added support [1] for the obsolete [2] AUTH LOGIN
method which enables aerc to send email via servers which remain common
in the wild.

Fixes ~sircmpwn/aerc2#263

Notmuch: be resilient to config errors

Right now notmuch panics if something goes wrong in the configure event.
This patch checks for that and returns an error instead, so that we can at least
get the UI up and running (and all the other accounts)

The experience will be completely degraded until another configure event occurs.
widgets/msgview: Reap the filter command

The filter command shells out and returns almost immediately. Call
Wait() so the filter process gets reaped. Prior to this patch, aerc
creates a zombie process for every email that is viewed.

Cleanup pager processes after closing a msgviewer

A pager is spawned every time an email is viewed but not killed off when
quitting the msgviewer, thus leading to process leakage. This patch
fixes this by adding a Close method to the msgview widget, which is
called in the close command.

Fix: oauthbearer runtime error

Configure an oauthbearer source without a token_endpoint
parameter would panic due to nil pointer dereference

  Example
    source=imaps+oauthbearer://frode.aa%40gmail.com@imap.gmail.com:993
    source-cred-cmd=pass oatuh2 frode.aa@gmail.com

token_endpoint is not required as it will use the provided
password as access_token when it is not set
