* inih is now widely available as a system library
* if not, a fallback from Wrap DB can be used

This issue was spotted on musl, where killing imv with the Q shortcut
while it was waiting for image paths in stdin led to the application
hanging until stdin received an EOF manually with ^D, since the stdin
stream was locked by the fgets() function.
Switching to pipes and a helper thread allows us to use read() for
reading from STDIN_FILENO while still taking advantage of the fgets()
logic for handling newlines and buffer size. read() is a thread
cancellation point (fgets() is only an optional one), which makes it
possible to cancel the helper thread cleanly and force the thread using
fgets() to exit when the write-end of the pipe it's reading from is
closed.
Since this isn't essential functionality, it's ok to simply not provide
it. In cases where XDG_RUNTIME_DIR was empty (but not unset) or set to a
directory where the user didn't have write permissions, socket creation
would fail and lead to segmentation faults in imv, due to the return
value of imv_ipc_create() not being checked.
Add newline to the prompt for reading paths from stdin.
Since string formatting isn't being used, it's possible to use fputs()
directly in the logging callback in imv.c.
split color_rgba into color_rgb and alpha
added configuration options to man pages
cleanup gitignore: the man pages output is now in the build directory,
so there is no to ignore man pages individually
* first steps for colored overlay
* overlay color wip
* add option for overlay position
if overlay_positiion_bottom is true overlay is at the bottom
* remove enum for overlay position
Previously, they would be sorted by however readdir returned them.
I suppose a proper configuration option to control sorting would be
nice, but for now, I think replacing forced random order with forced
alphabetical order is an improvement.
mmap with MAP_SHARED would fail if the compositor provides a read-only
descriptor with keymap. And at least weston applies F_SEAL_WRITE to the
memfd if supported by the platform.
Fixes#263
Calling `rsvg_handle_close` doesn't do anything here because the handle
is already constructed with data or file. `g_object_unref` is called
instead to free memory.
Rotation can be done by any amount (not limited to multiples of 90).
Commands allow flipping horizontally and vertically.
The flips are done relative to the current rotation.
