27c64db6df build-sys: use linux/memfd.h if available
linux/memfd.h was added linux 3.17, so it might not be widely
available for a while.

Also, check if memfd_create is defined, for the HAVE_LINUX_MEMFD_H
check to have a chance of succeeding.

Also, collapse all ifdefs for memfd-related stuff, because they
were all added together so there's no need to check separately.

64845bdc82 ask-password: Add --echo to enable echoing the user input
Programs such as OpenVPN may use ask-password for not only retrieving
passwords, but also usernames.  Masking usernames with * seems just silly.

 v2 - Don't mess with termios flags, instead print the input
      instead of an asterix.  Resolves issues with backspace
      and TAB input.

 v3 - Renamed 'do_echo' variables and argument to 'echo'.  Also
      modified the ask_password_{tty,agent,auto} API instead of
      additional wrapper functions.

[zj: undo changes to ask_password_auto, since no callers were using
     the new argument.]

62d5068d63 terminal/idev: don't remove consumed-mods from kbd-matches
XKB consumed mods include modifiers that *didn't* affect the translation,
but might affect it if used. This is very misleading, given that we are
usually not interested in that information. Therefore, keep them in real
mods to behave like X11 does. Maybe at some point, XKB introduces proper
shortcut matching...

Also make evcat display consumed modifiers so we can better debug those
situations.

34dbefceb1 terminal/screen: perform bold->light conversion only on foreground
Bold glyphs always use light colors. However, this color conversion is
limited to the foreground color, so skip it for backgrounds.

378c4eed02 terminal/subterm: leave bold-light conversion to parent
We rely on the parent terminal to do color conversion, so also leave
bold->light conversion to the parent. Otherwise, it will be performed
twice and we might apply it on the wrong color.

3ae49a8fdb terminal/screen: save state in separate object
Terminal state can be saved/restored by applications. To simplify our

Especially with alternate screen buffers, this will simplify our code

9ed6e68e52 terminal/subterm: skip setting parent's cursor
We draw our own cursor in subterm now, so there's no reason to update the
cursor-position of the parent terminal on each frame. The parent's cursor
is hidden, anyway.

ce7b9f50c3 console: add user console daemon
This adds a first draft of systemd-consoled. This is still missing a lot
of features and does some rather primitive rendering. However, it shows
the direction this code is going and serves as basis for further testing.

The systemd-consoled binary should be run as `systemd --user' unit. It
automatically picks up any session marked as Desktop=SYSTEMD-CONSOLE.
Therefore, you can use any login-manager you want (ranging from /bin/login
to gdm) to create sessions for systemd-consoled. However, the sessions
managers must be prepared to set the Desktop= variable properly.

The user-session is called `systemd-console', only the daemon providing
the terminal environment is called `systemd-consoled' (mind the 'd').

So far, only a single terminal session is provided on each opened
user-session. However, we support multiple user-sessions (even across
multiple seats) just fine. In the future, the workspace logic will get
extended so you can have multiple terminal sessions in a single
user-session for easier access.

Note that this is still experimental! Instructions on how to run it will
follow shortly.

48fed5c55b pty: optimize read loop
As it turns out, I can actually send data to the pty faster than the
terminal can read. Therefore, make sure we read as much data as possible
but bail out early enough to not cause starvation.

Kernel TTY buffers are 4k, so reduce the overall buffer size, but read
more than once if possible (up to 8 times sounds reasonable).

ce04e2335a terminal/screen: adjust screen age only on update
Instead of increasing the screen-age on redraw, we now increase it only on
real updates. This is effectively the same, but avoids increased age
counters on backbuffer rendering. Therefore, we can now check age counters
against fronbuffers safely, while rendering frames in background.

56dec05d29 terminal/screen: add color converter
Terminals use pseudo color-codes mixed with 8bit and 24bit colors. Provide
a color-converter so external renderers only have to deal with ARGB32
colors.

This requires a color-palette as input as there's no fixed mapping. We
provide a default, but maybe we wanna support external palettes in the
future.

cad8fe9a2b terminal/screen: add cursor rendering
This is the most simple way to render cursors: flip attr->inverse of the
cursor cell. This causes the background and foreground colors of the
cursor-cell to be inversed.

Now that we render cursors ourselves, make subterm not call into the
parent terminal to render cursors.

884964a963 terminal/idev: add helper to match keyboard shortcuts
Matching keyboard shortcuts on internationalized keyboards is actually
non-trivial. Matching the actual key is easy, but the modifiers can be
used by both, the matching and the translation step. Therefore, XKB
exports "consumed-modifiers" that we use to figure out whether a modifier
was already used by the translation step.

The new IDEV_KBDMATCH() helper can be used to match on any keyboard
shortcut and it will do the right thing.

61d0326a5b terminal/unifont: add built-in fallback glyph
In case we cannot render a glyph, we want a fallback we can display
instead. If we rely on the font itself to provide the fallback character,
we have nothing to display if that character is not available. Therefore,
add a static fallback that we can use at any time.

51cff8bded terminal/grdev: provide front and back buffer to renderers

aec3f44651 terminal/drm: provide pipe->target() callback
Instead of looking for available back-buffers on each operation, set it to
NULL and wait for the next frame request. It will call back into the pipe
to request the back-buffer via ->target(), where we can do the same and
look for an available backbuffer.

This simplifies the code and avoids double lookups if we run short of
buffers.

f1f5b2a3bd terminal: make utf8 decoder return length
Lets return the parsed length in term_utf8_decode() instead of a buffer
pointer. Store the pointer in the passed argument.

This makes it adhere to the systemd coding-style, were we always avoid
returning pointers, but store them in output arguments. In this case, the
storage is not allocated, so it doesn't fit 100% to this idiom, but still
looks much nicer.

1c92ff85b7 bootchart: use 'n/a' if PRETTY_NAME is not found
Spotted with coverity. If parsing both /etc/os-release and
/usr/lib/os-release fails then null would be passed on. The calls
to parse the two files are allowed to fail. A empty /etc may not
have had the /etc/os-release symlink restored yet and we just
try again in the loop. If for whatever reason that does not happen
then we now pass on 'n/a' instead of null.
