db39ca181a dirtree: add dirtree-collapse config setting
Adds a setting to the configuration to choose at which level the
folders in the dirtree are collapsed by default.

In my case, this is useful because my organisation has some rather deep
nesting in the folder structure, and a _lot_ of folders, and this way I
can keep my dirtree uncluttered while still having all folders there if
I need them.

ca90343850 outgoing-cred-cmd: delay execution until an email needs to be sent
This can be useful in cases when:

1. outgoing-cred-cmd requires a user action or confirmation (e.g. when
   using pass with a Yubikey or similar smart card that requires a user
   to enter a pin or touch the device when decrypting the password)

2. A user starts aerc frequently, but not all the sessions end up with
   sending emails

3. So the user only wants to execute outgoing-cred-cmd when the password
   is really used, so the user doesn't have to enter pin or touch their
   Yubikey each time aerc starts

54a0a377e0 threads: debounce client-side thread building
Debounce client-side thread building in the message store. Debouncing is
useful when multiple messages are loaded, i.e. when scrolling with
PgUp/PgDown.

Without the debouncing, all client-side threads will be built everytime
the message store is updated which creates a noticable lag in the
message list ui when client-side threading is activated.

The default debouncing delay can be changed by changing
'client-threads-delay' in the UI config section.

ccd042889f threading: add force-client-threads option
This patch adds a config option to force the use of client side threads.
This option will override a servers Thread capability, and only build
threads on the client. It can be enabled contextually. For example:

	[ui]
	threading-enabled = true

	[ui:folder~^Archive]
	force-client-threads = true

This config would enable threads for all views, and use client threads
for folders that start with Archive. This can be advantageous if, for
example, the folder is very large and the server has a slow response due
to building threads for the entire mailbox

4240f1fbfd perf: reduce calls to GetUiConfig
GetUiConfig was being called many times, and came up as a high CPU user
in a cpuprofile. Every call would merge a UIConfig, which is a costly
operation. Ideally, we would only need to have a config for every
account X every directory. We also have a context for subjects. This
patch stores all FOLDER and ACCOUNT level configs and reuses those
merged objects. The SUBJECT contexts are not stored in favor of merging
on-the-go, with a TODO comment to deprecate that feature and implement a
better per-message styling option. I suspect this feature is not used
very much.

Before applying this patch with my setup, GetUiConfig is called 1159
times just to open aerc. After applying, this is reduced to 37.

de24d2d590 config: fix setting of zero-value time.Duration config values
When using section.MapTo(struct) (go-ini), if the struct has a default
value for a time.Duration type, a zero-value in the config will not
overwrite the default. If the type is *time.Duration, it will be
overwritten properly. One consideration was to change all
time.Duration types to *time.Duration. This method was chosen for ease
of implementation.

For example, if you set dirlist-delay = 0s, the delay will be 200ms.
This can be observed by logging the value just after mapping the ui
section in config.go. A config value of 0.1ms will have a delay of
0.1ms.

Currently, aerc has 4 time.Duration config values:
1. DirlistDelay - default 200 ms
2. CompletionDelay - default 250 ms
3. CheckMail - default unset (0)
4. CheckMailTimeout - default 10 s

1, 2, and 4 have a non-zero default value and are subject to this bug.
Only 1 and 2 are fixed in this patch. Number 4 would not make sense to
have a 0 second timeout, therefore we can prevent the user from doing
this by keeping it as it is.

Another option could be to set these to 0 in config.go. The default
config (aerc.conf) has these keys in it with their default values.
Presumably, we don't need to set them again in config.go. If a user
deletes the config values out of aerc.conf, the UI will function but
with 0s delays.

83e0e2638d msgviewer: parse and display authentication results
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.

An optional timeout can be used with maildir/notmuch. Default is 10s

New account options:
check-mail
check-mail-cmd (maildir/notmuch only)
check-mail-timeout (maildir/notmuch only), default 10s
check-mail-include (IMAP only)
check-mail-exclude (IMAP only)

57699b1fa6 feat: add gpg integration
This commit adds gpg system integration. This is done through two new
packages: gpgbin, which handles the system calls and parsing; and gpg
which is mostly a copy of emersion/go-pgpmail with modifications to
interface with package gpgbin. gpg includes tests for many cases, and
by it's nature also tests package gpgbin. I separated these in case an
external dependency is ever used for the gpg sys-calls/parsing (IE we
mirror how go-pgpmail+openpgp currently are dependencies)

Two new config options are introduced:
* pgp-provider. If it is not explicitly set to "gpg", aerc will default to
it's internal pgp provider
* pgp-key-id: (Optionally) specify a key by short or long keyId

'/', to easily enter "less" search mode. When in the passthrough mode,
all bindings are ignored by default. The default binds.conf only defines

c77a1c5d9d config: expand tilde in search directories
Will expand a user-provided custom sharedir, XDG_CONFIG_HOME and
XDG_DATA_HOME if necessary. Will not alter those strings if they do not
begin with a tilde.

0cfffaef54 config: specify sharedir during build
We should use the Makefile value of SHAREDIR when searching for config
files and templates etc.

This is important for systems which do not use the standard file
hierarchy or which do not have a consistent location for installing
program files, for example NixOS, which will have a different install
location with every update.
