Refactor the filtering and paging logic to use several fewer goroutines.
Fixes data race condition with the timing of filter -> pager ->
terminal, can be found when switching message views fast.
Check if filter -> pager process is currently running before calling it
to start again. Fixes data race between fetching message body and
terminal starting. Both can initiate the copying process, and for long
running filters and fast message fetching, it is possible to have
fetched a message but still be running the filter when the terminal
starts.
Move StripAnsi to it's own file in lib/parse, similar to the hyperlinks
parser.

To allow referencing built-in filters without hard coding a path during
installation, append the following folders to the exec PATH when running
the filter commands:
~/.config/aerc/filters
~/.local/share/aerc/filters
$PREFIX/share/aerc/filters
/usr/share/aerc/filters
If a filter script has the same name than a command in the default exec
PATH, it will not shadow it. In that edge case, the absolute path to the
filter script must be specified.

Subsitute the format specifier %w for %v in the logging facility. The
logging functions use a fmt.Sprintf call behind the scene which does not
recognize %w. %w should be used in fmt.Errorf when you want to wrap
errors. Hence, the log entries that use %w are improperly formatted like
this:

A race condition can occur when a PartViewer is closing and also working
on a draw. The closing process sets the terminal to nil, which will
create a panic. This can be tested in development by setting the timer
in the main aerc tick loop to something very low (1 ms for example).
One other unprotected call to terminal exists in the composer widget.
Check that the terminal is not nil before calling methods on it.

The terminal widget already handles most boring stuff: unwatch terminal
events, kill the underlying process, wait for it to exit, etc. Call the
Close() method and be done with it.
This avoids issues where the embedded terminal widget is destroyed but
the pager process does not know about it and dies in agony, writing over
aerc's UI:
Vim: Caught deadly signal HUP
Also, it may avoid leaving child processes as zombies without giving
them a proper burial.

Replace go-libvterm package with tcell-term. go-libvterm provides the
embedded terminal for aerc. It uses a statically linked C library,
requiring CGO.
tcell-term is written in pure go and is written to be portable with
tcell applications by implementing the tcell Widget interface. This
allows the terminal to take a view (which aerc already supplies) and
draw directly to it, as well as issue tcell Events to a Watcher.

Parse the Authentication-Results header and display it in the message
viewer (not enabled by default). DKIM, SPF and DMARC authentication
methods are supported. Implement recommendation from RFC 7601 Sec 7.1 to
have an explicit list of trustworthy hostnames before displaying the
authentication results. Be aware that the authentication headers can be
forged.
To display the results for a specific authentication method, add the
corresponding name to the layout of headers in the viewer section of
aerc.conf, e.g. to display all three, use:
header-layout = From|To,Cc|Bcc,Date,Subject,DKIM|SPF|DMARC
More information will be displayed when "+" is appended to the
authentication method name, e.g. DKIM+ or SPF+ or DMARC+.
Also, add the trustworthy hosts per account with the trusted-authres
parameter, e.g.
trusted-authres = *
to trust every host or use regular expressions for a finer control.
Multiple hosts can be entered as a comma-separated list. Authentication
results will only be displayed when the host is listed in the
trusted-authres list.

When trying to search in less, keys bound to viewer functions can't be
used as part of the search query, which makes the search useless.
Add a view::passthrough binding mode and a :toggle-key-passthrough
command go toggle in and out of that mode. By default, typing '/' in the
viewer is bound to enabling key passthrough and automatically inserting
'/', to easily enter "less" search mode. When in the passthrough mode,
all bindings are ignored by default. The default binds.conf only defines
a single keybinding in that mode: <Esc> to get back out. $ex is bound to
<C-x> to allow typing colons.

Also update to the tcell v2 PaletteColor api, which should keep the chosen

Note, that if $TRUECOLOR is defined and a truecolor given, aerc will now stop
clipping the value to one of the theme colors.
Generally this is desired behaviour though.
This allows us to hook into the std libs implementation of parsing related stuff.
For this, we need to get rid of the distinction between a mailbox and a host
to just a single "address" field.
However this is already the common case. All but one users immediately
concatenated the mbox/domain to a single address.
So this in effects makes it simpler for most cases and we simply do the
transformation in the special case.

Aerc usually used the path []int{1} if it didn't know what the proper path is.
However this only works for multipart messages and breaks if it isn't one.
This patch removes all the hard coding and extracts the necessary helpers to lib.
The grid used static sizes which meant that changing settings didn't
have an effect on elements of the ui, notably the sidebar width. This
patch makes the `Size` parameter of a cell a function which returns the
`int`, allowing for dynamic sizes.
A `Const` function is also included for ease of use for static sizes.
The following functionalities are added to configure aerc ui styles.
- Read stylesets from file with very basic fnmatch wildcard matching
- Add default styleset
- Support different stylesets as part of UiConfig allowing contextual
styles.
- Move widgets/ui elements to use the stylesets.
- Add configuration manual for the styleset
