The printf() format specifier "%m" is a glibc extension to print
the string returned by strerror(errno). While supported by other
libraries (e.g. uClibc and musl), it is not widely portable.
In Weston code the format string is often passed to a logging
function that calls other syscalls before the conversion of "%m"
takes place. If one of such syscall modifies the value in errno,
the conversion of "%m" will incorrectly report the error string
corresponding to the new value of errno.
Remove all the occurrences of the specifier "%m" in Weston code
by using directly the string returned by strerror(errno).
While there, fix some minor indentation issue.

ef57a9b788 added support for window operations such as reporting the
title in escape mode. It implemented this by which-window-op case,
inside the existing which-escape-code case. Whilst it would break out of
the former window-op case, it never broke out of the latter escape-code
case. This would lead to window ops (such as reporting title) falling
through to restoring the saved cursor position.
This doesn't seem at all right, and also fixes a warning with GCC 8.

'I found it weird that the compiler wouldn’t see that, so I re-checked

I think with -O3, this specific "for" is compile-time unlooped, and
utf8_next_char inlined. And there is *one* path that can keep
machine.state to utf8state_start, thus triggering the warning.
Without -O3, the function is globally tagged as “changing unicode”, so
no warning is produced.

weston-terminal intermittently crashes on startup. This occurs because
some parameters in the weston_terminal structure such as data_pitch,
don't get set to non-zero until the resize_handler() callback gets
triggered. That callback makes a call to terminal_resize_cells(), to
calculate the proper values for these parameters.
On occasion, the resize handler call is slow to resolve, and the program
proceeds to start processing characters for the terminal window. With
the parameters defaulting to zero, certain calculations come out wrong,
leading the program to attempt to scroll the buffer when it shouldn't,
and thus follows the crash.
Instead, force the call to terminal_resize_cells() during the init, with
some dummy defaults, to ensure the parameters are always non-zero.

So it turns out if you cat /dev/urandom and drag select in the mess
you can crash weston-terminal. There may also be more legitimate
ways of doing this.
The reason is that isalpha() and isdigit() only accept values that
fit within an unsigned char or are EOF.
By treating values < 0 the same as values > 127 we prevent this crash.

We have the Weston command line option '--no-config' which is meant to
prevent loading weston.ini at all. It works for Weston itself, but it
does not work for any clients that also want to read weston.ini.
To fix that, introduce a new environment variable WESTON_CONFIG_FILE.
Weston will set it to the absolute path of the config file it loads.
Clients will load the config file pointed to by WESTON_CONFIG_FILE. If
the environment variable is set but empty, no config file will be
loaded. If the variable is unset, things fall back to the default
"weston.ini".
Note, that Weston will only set WESTON_CONFIG_FILE, it never reads it.
The ability to specify a custom config file to load will be another patch.
All programs that loaded "weston.ini" are modified to honour
WESTON_CONFIG_FILE.

Add a new state_changed_handler callback to the window to know when the
window has changed state; the terminal will use this to know when the
window started and ended its resize operation, and modify the terminal's
titlebar accordingly.
This ensures the allocation results are checked for NULL (out of
memory), and terminates the program in such a case.

weston-terminal uses RLE (U+202B) as a placeholder of the right half
of a double width character. However, not all fonts include this
glyph and cairo renders it as .notdef (glyph index 0) in that case.
When resizing the terminal, it shows the grid size in the titlebar.
We reset the title next time we get an enter event. This patch makes
sure we only reset the title the first time we enter after a resize.
Handles potential out of memory situation by skipping the title update.

It seems that this was only used by the popup menu infrastructure,
which can handle this all on its own. Implementing e.g. transients
in the future can be done with a simple xdg_shell_set_transient_for.
We don't have a reliable way to know when to clear this indicator.
Typically the pointer will still be over the window when the resize is
done and we'll get an enter event, but if the window sets a max size
the pointer may be over another window when the resize is done.
We'll need a new wl_shell (or more likely xdg_shell) event for this.
