The X11 lock file was somewhat opaque. Into a sized array of 16
characters, we previously read 11 bytes. 61beda653b fixed the parsing of
this input to ensure that we only considered the first 10 bytes: this
has the effect of culling a LF byte at the end of the string.
This commit more explicitly NULLs the entire string before reading, and
trims trailing LF characters only.
It also adds some documentation by way of resizing pid, an explicit size
check on snprintf's return, and comments.
Verified manually that it emits lock files with a trailing \n, as Xorg
does. Also verified manually that it ignores misformatted lock files,
but accepts either \n or \0 in the trailing position.

If we destroy the text_input (e.g. due to surface deactivation) whilst
the IM manager (the client holding the input_method_context resource,
usually weston-keyboard) sends an event, we can hit a segfault in
text-backend. This is because we free the text_input structure, but
don't actually clear the context->input structure even when we send the
deactivate event.
This is clearly intended to be catered for, since context->input is
always checked for NULL before we relay any events.
This is enough to fix one cause of text-test failing, but it's
ultimately error-prone until we have a no-op test-shell; there is still
a race where weston-desktop-shell can launch weston-keyboard before
text-test manages to bind zwp_text_input_manager.

Patch 139fcabe7c "xwayland: Improve error
checking for strtol call" caused a regression in the X11 unix socket
lock file parsing. Before that patch, only the first 10 characters were
considered for parsing. After the patch, the newline as the 11th
character caused strtol() to stop parsing at the 10th character which
was then considered an error as not the whole input was consumed.
The effect of the regression was that no X11 lock files were ever deemed
stale, hence stale lock files were never removed. Up till now, I have
accumulated 37 lock files, and Weston complaining for each of them on
every start it cannot parse them.
Fix this by terminating the string at the expected newline character.
Also, it looks like 'pid' was being used uninitialized, risking strtol()
reading past the end of the array. This patch fixes that too.

If only the source of a viewport is set, the width and height must
be integer or the protocol mandates that the compositor generate an
error. This is because using only the source is a crop, and the
width and height become the surface size - all surface sizes must
be integer.
Weston was fixed to generate this error in bb32ccc0, however the
test app continued to use fractional co-ordinates when run as
weston-scaler -s (which only sets the viewport source)
This leaves fractional width/height for the other cases, but uses
integer for the crop-only mode. The descriptions in the help text
are still accurate with this change, but weston-scaler -s no longer

This adds single-symbol compose support using libxkbcommon's compose
functionality. E.g., assuming you have the right alt key defined as
your compose key, typing <RAlt>+i+' will produce í, and <RAlt>+y+= will
produce ¥. This makes compose key work for weston-editor,
weston-terminal, weston-eventdemo, and any other clients that use
Weston's window.* routines for accepting and managing keyboard input.
Compose sequences are loaded from the system's standard tables. As
well, libxkbcommon will transparently load custom sequences from the
user's ~/.XCompose file.
Note that due to limitations in toytoolkit's key handler interface, only
compose sequences resulting in single symbols are supported. While
libxkbcommon supports multi-symbol compose strings, support for passing
text buffers to Weston clients is left as future work.
This largely obviates the need for the weston-simple-im input method
client, which had provided a very limited compose functionality that was
only available in clients implementing the zwp_input_method protocol,
and with no mechanism to load system or user-specified compose keys.
