ngui,nd: screenlock feature implementation
ci/woodpecker/push/woodpecker Pipeline was successful Details
ci/woodpecker/tag/woodpecker Pipeline was successful Details
the screenlock use case is a way to restrict access to the touchscreen,
for example from children. it is in no way a security measure against
theft or prolonged physical access.

however, nd daemon will refuse to connect to a wifi, switch sysupdates
channel, set a new nodename or init lnd wallet during active screenlock

screenlock pin code can be enabled and disabled from the settings screen.
upon loss of the code, the only way to disable screenlock is to set
slock field to null in the nd daemon conf file.

nd,ui: add a new facility to be able to change node name
ci/woodpecker/push/woodpecker Pipeline was successful Details
ci/woodpecker/tag/woodpecker Pipeline was successful Details
the "nodename" encompasses lnd alias and OS hostname.
while the former may be seen by lightning node peers as a node name, the
latter is how the device is seen on a local network such as WiFi.

upon receiving a comm message set_nodename, nd sets both lightning node
alias and hostname to that new name while applying restrictions such as
RFC 1123 for hostnames.

the lightning alias is written to lnd config file, regenerated and
persistent, after which the lnd daemon is restarted to pick up the
changes. network host name is changed by writing the name to
/etc/hostname and issuing "hostname <newname>" shell command.

while persisting operations are atomic, the whole sequence isn't.
in the latter case an inconsistency can be eliminated by sending a
set_nodename msg again.

the nd daemon also includes the OS hostname in the settings message when
sending it to ngui.

ui: add zig wrapper funcs for keyboard on/off
ci/woodpecker/push/woodpecker Pipeline was successful Details
this is still someone limiting in that tabview invariance is assumed.
so, it'll require some more to make it work for a screen pop over in the
future.

test: reinstate lndhc playground build
it broke after last commit where lnd client got moved into the lightning
module, preventing lndhc from importing it.

also, add lndhc to CI build to catch regressions like this early on.

ui/driver: add Xlib support when dev-building on a linux host
ci/woodpecker/push/woodpecker Pipeline was successful Details
something broken in recent SDL2 or Xorg releases, or a combination of
plus LVGL usage of their APIs. the result was that the main window
stopped drawing altogether. Downgrading SDL2 and other parts didn't seem
to help at all.

this commit adds support for SDL2-alternative when compiling and running
the GUI on a dev linux machine with Xorg.

there's a small patch to the original lv_drivers/x11/x11.c since clang
in C11 mode refuses to compile otherwise, giving a "initializer element
is not a compile-time constant" error.

release builds remain as is. this is only for development.

nd,ngui: add lightning setup process, phone pairing and reset
ci/woodpecker/pr/woodpecker Pipeline failed Details
ci/woodpecker/push/woodpecker Pipeline was successful Details
ci/woodpecker/tag/woodpecker Pipeline was successful Details
the daemon can now identify which state lnd is in and report to the GUI
which displays different elements on the lighting tab, based on the
reported lnd state:

- startup in progress: displays spinner
- no lightning wallet: displays a "setup" button and guides the user
  through a simple workflow
- reset an operational node

this means, the UI has now minimal but functional elements for any user
equipped with a smart phone to set up the lightning node without SSHing
in or using command line in general.

allocator.

while there, improved a bit overall memory handling by making sure
heap-alloc'ed messages are always deinit'ed.

another source of trouble was logging from within a sighandler: the
logger uses a thread mutex which may deadlock when the handler is
invoked by the OS.

comm: introduce a simpler way to read/write
this builds on top of the main read and write fn, setting up a global
structure to allow module users imply comm.pipeWrite(msg)
and comm.pipeRead() without providing an allocator or reader/writer
on each call.

the advantage is simplification in the gui functions because they don't
have access to an allocator or the nd process read/write pipe.

disadvantage is in testing because it requires a global,
"before all tests" setup.

at the moment, only ngui is modified to use the new pipeRead/Write. the
daemon would suffer too many changes, especially in tests, due to the
global state.

a previous commit added some lightning tab implementation which

this commit queries lnd for a wallet balance and displays it on the
bitcoin tab since "wallet" funds are on-chain and it doesn't feel like
it belongs to the lightning tab in the UI.

while there, also improved some daemon backend code style, alightning

ngui: clarify and handle concurrency during screen sleep/standby
ci/woodpecker/pr/woodpecker Pipeline was successful Details
ci/woodpecker/push/woodpecker Pipeline was successful Details
ci/woodpecker/tag/woodpecker Pipeline was successful Details
the screen.sleep fn was actually called in concurrent-unsafe mode,
i.e without acquiring UI mutex. in conjuction with commThreadLoopCycle
this would have eventually led to LVGL primitives concurrent access.

so, screen.sleep now takes UI mutex to hold during LVGL calls.
a bit ugly but certainly better than relying on luck.

ui/lvgl: improve UI element types in zig
ci/woodpecker/push/woodpecker Pipeline was successful Details
this commit improves on the LVGL API wrapping interface in zig by
defining different types where each is associated with either a
particular lv_xxx_t object in C or a logically different UI element.

this makes programming much more pleasant, allows compartmentalizing
different UI concepts and elements, and reduces chances of making a
thanks to stricter type enforcement.

no visual changes in the UI.

ui: force alignment of modal callback function

ci/woodpecker/tag/woodpecker Pipeline was successful Details
fullscreen modal dialog was added in 4297c139. the callback function to
that modal *must* be aligned according to the target architecture.
failing to do so may result in "incorrect alignment" panic.

this somehow worked in 4297c139 but sometimes panic. i suspect this may
be due to PIE-enabled build, possibly in conjuction with some zig v0.10
compiler bugs.

most troubles were due to blocking nature of child process pipe

build: add semantic versioning support
both nd and ngui now acquire semantic versioning recorded at the build
time. they also report the version at startup and -v flag.
this is useful for a release process and to avoid potential
compatibility issues in the future.

in a regular build flow, the version is taken from a git tag using the
following command:

    git -C . describe --match 'v*.*.*' --tags --abbrev=8

in a non-standard scenario where git isn't available, the version can
be provided on the command line during build like so:

    zig build -Dversion=1.2.3

if both git and command line supplied versions are available, they must
match.

this commit includes lots of new code in ui/lvgl.zig and ui/widget.zig

in addition, a new module ui/widget.zig is where all custom UI elements
will reside. at the moment it comprises of the ported topdrop and a new
modal func. the latter is an alternative to LVGL's lv_msgbox popup.

as a practical example, the commit replaces the power off confirmation
popup with the new modal window.
