Commit 27425c15c4 ("autocompletion: fix slice out of bounds access")
introduced a regression in the autocompletion that messes up the order
of last entered chars when autocompletion runs.
The ranges for a slice a[low:high] are 0 <= low <= high <= len(a) [0]
To reproduce with the ":cf" command:
1) enter ":c"
2) wait for autocompleteion
3) enter "f"
4) the prompt will now be ":fc"

Protect the access to the tabs array and current index with a mutex.

The Tabs object exposes an array of Tab objects and the current selected
index in that array. The these two fields are sometimes modified in
goroutines, which can lead to data races causing fatal out of bounds
accesses on the tab array.
Hide these fields as private API. Expose only what needs to be seen from
the outside. This will prepare for protecting concurrent access with
a lock in the next commit.

This reverts commit d7feb56cbe.
This commit introduced a regression in which upon closing any but the
last tab caused an out of range panic would occur.
Steps to reproduce
- open a tab
- open another tab
- close the first tab

This change fixes a panic caused by the selected tab being out of sync
when selecting a new one in widgets.(*Aerc).SelectedTab(). This happens
if the tab is already removed from the list of tabs, but the selection
not yet being updated.
This was achieved by moving the tabs behind updating the selection.

Add check for public keys of all message recipients (to, cc, and bcc)
before sending the message. Adds an OnFocusLost callback to header
editors to facilitate a callback for checking keys whenever a new
recipient is added (OnChange results in too many keyring checks).
Once encryption is initially set, the callbacks are registered. If a
public key is not available for any recipient, encryption is turned off.
However, notably, the callbacks are still registered meaning as s soon
as the user removes the recipients with missing keys, encryption is
turned back on.

I'm not entirely sure what the interactions are between the terminal
emulator, aerc's grid, and the space that moves around when the tab bar
disappears because there are no more tabs, but this fixes the issue 100%
of the time and I haven't noticed any issues.

Since panics still regularly "destroy" the terminal, it is hard to get a
stack trace for panics you do not anticipate. This commit adds a panic
handler that automatically creates a logfile inside the current working
directory.
It has to be added to every goroutine that is started and will repair
the terminal on a panic.

as per the discussion https://lists.sr.ht/~sircmpwn/aerc/patches/15367
this handles completions in `completer/completer.go` by enabling the
completer to return a `prefix` that will be prepended to the selected
completion candidate.
New border-char-horizontal and border-char-vertical config settings in
aerc.conf allow users to modify border appearance from the default
1-wide/tall blank space. In stylesets, border.fg now affects the
foreground color when custom characters are defined.

Also update to the tcell v2 PaletteColor api, which should keep the chosen
theme of the user intact.
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.
Introduce the ability to configure stylesets, allowing customization of
aerc's look (color scheme, font weight, etc). Default styleset is
installed to /path/to/aerc/stylesets/default.

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
This adds the commands pin-tab and unpin-tab. Once pinned a tab lives on
the left of the tabstrip and has a configurable marker, defaulting to `
before its name.
Before, pressing <Enter> when completions were visible would execute the
selected completion. As soon as completions were provided, the first
item would be selected. This could cause issues e.g. when changing
folders:
:cf <Enter>
Previously, this would have selected the first folder in the list. Now,
since <Tab>, <C-n>, etc have not been pressed to select the first
completion, the command above simply executes `:cf `.
To accomplish this, a "no-op completion" has been added at index -1.
Rather than showing completions inline in the text input, show them in a
popover which can be scrolled by repeatedly pressing the tab key. The
selected completion can be executed by pressing enter.
A popover is a special UI element which can be layered over the rest of
the UI (i.e. it is painted last) and can fall anywhere on the screen,
not just with the bounds of its parent's viewport/context. With these
special abilities comes the restriction that only one popover may be
visible on screen at once.
Popovers are requested from the UI context passed to Draw calls and
specify the anchor point and the desired dimensions. The popover is then
fit to the available space and placed relative to the anchor point.
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.
Previously removing a tab would always pop from the history of tabs.
This checks to see if the closing tab is the one selected, if it is then
we use the history, otherwise we only need to change the selected tab if
it was after (to the right of) the closing tab, in which case we just
decrement the selected index.
This adds the Mouseable interface. When this is implemented for a
component that item can accept and process mouseevents.
At the top level when a mouse event is received it is passed to the
grid's handler and then it trickles down until it reaches a component
that can actually handle it, such as the tablist, dirlist or msglist.
A mouse event is passed so that components can handle other things such
as scrolling with the mousewheel. The components themselves then perform
the necessary actions.
Clicking emails in the messagelist opens them in a new tab.
Textinputs can be clicked to position the cursor inside them.
Mouseevents are not forwarded to the terminal at the moment.
Elements which do not handle mouse events are not required to implement
the Mouseable interface.
Choose the readline defaults for the behavior of these two
functions/keybindings. Depending on the program, either of these can
delete the whole line.
Note that by default in [compose], <C-k> is bound to :prev-field<Enter>.
Leave it up to the user whether or not they want to rebind the key in
[compose].
Add a "new-message-bell" option to the UI section of aerc.conf. A new
hook into the message store allows the msglist widget to detect new
messages being added to the displayed list. When new messages are
delivered, and the new-message-bell option is enabled (as it is by
default), the terminal will beep.
Tabstrip didn't take into account the width of the context. Now, it just
shows as many tabs as can fit and truncates the last one if necessary.
In future it probably would be best to ensure that the selected tab is
rendered on the screen.
This adds tab completion to textinput components. They can be configured
with a completion function. This function is called when the user
presses <tab>. The first completion is initially shown to the user
inserted into the text. Repeated presses of <tab> or <backtab> cycle
through the completions list. The completions list is invalidated when
any other non-tab-like key is pressed.
Also changed is some logic for current completion generation so that
all available commands are returned when <tab> is pressed with no
current text and similarly for arguments of commands.
