This small helper allocates a string big enough to hold the whole u8
string. This should be used for short and temporary strings only! It
allocates way to much memory for bigger or long-living strings.

We really need xkbcommon-keysyms.h for building kmscon/uterm/TSM/etc.
However, the recent fix was ugly and didn't really help. Instead we copy
the keysyms file into external/xkbcommon/ so we can just include the real
xkbcommon files from any source but have a fallback in external/.
Hence, you can still build kmscon without xkbcommon with this fallback,
but this will be removed the first day when xkbcommon sees a public
release.

We never checked the memory helpers for errors because they used to be
from glib. However, with our own helpers we need to check for errors to be
sure.

This adds a helper that removes entries from a hashtable. This hasn't been

Add three helpers to create and manage symbol-tables. Also fix internal
default-table to use them.

This helper function may be useful to other external code and allows us to
always return UCS4 strings. Other code can then use this helper to convert
it into UTF8.

We should avoid any global state in shared libraries. As the TSM code is
becoming a shared library, we definitely need contexts for symbol tables.
However, we don't want to fix up all code now so we use a default table
NULL instead.
This can be fixed later but is ok for now.

We changed the PPI value to 96 so the default font size looks abnormally
large now. Reset it to the previous value of 12 so it is more "normal".
Signed-off-by: David Herrmann <dh.herrmann@googlemail.com>
This adds a new option to force a global PPI for all fonts. This overrides
per monitor PPI values.
This is useful if monitors do not provide correct PPI values and we want
the same behavior as all other X11 apps (which is 96 PPI forced).
Internally we speak of "Pixels per Inch" as this is more correct. However,
to not confuse users we use the more common term "Dots per Inch".
This also changes the default PPI value from 72 to 96. 96 is the de-facto
default value on linux so we should use it, too.

If Shift is hold while F4 to F20 is pressed, a second parameter is added
to the sent CSI sequence. Implement this according to all other major
terminal emulators. This is no official DEC feature, though.
Thanks to "Etam" for reporting this!
Signed-off-by: David Herrmann <dh.herrmann@googlemail.com>
No DEC-VT-manual seems to describe this feature, however, nearly all
terminal emulators stop parsing OSC strings when receiving a BEL
character. So add this to the normal ST character to terminate OSC
strings.
Many thanks to Ran Benita for reporting and investigating into this.

XTerm's altSendsEscape resource controls whether an escape character is
prepended to any output that is generated by keyboard input. We enable it
by default now.
Keyboard handling becomes kind of ugly now in the VTE layer. We should
definitely change this into some kind of lookup table or a more
sophisticated switch() handler in vte_input.c or similar.
Thanks to Tobias Wolf, "Etam" and Ran Benita for reporting this to the
bug-tracker and figuring out how this is correctly handled.

Instead of requiring to use uterm_screen objects we now add a
fake_blendv() request directly to the display object. We rename it to
"fake_blend" instead of just "blend" so we can later implement real
blending.
This reuses the existing infrastructure. But the fake_blendv is the way to
go so we rename the existing functions to "fake_*" either.

Instead of requiring to use a uterm_screen object we now also add these
