Kevin Wolf 6e1db57b2a qemu-char: Print strerror message on failure
The only way for chardev drivers to communicate an error was to return a NULL
pointer, which resulted in an error message that said _that_ something went
wrong, but not _why_.

This patch changes the interface to return 0/-errno and updates
qemu_chr_open_opts to use strerror to display a more helpful error message.

Paolo Bonzini 7447545544 change all other clock references to use nanosecond resolution accessors
This was done with:

    sed -i 's/qemu_get_clock\>/qemu_get_clock_ns/' \
        $(git grep -l 'qemu_get_clock\>' )
    sed -i 's/qemu_new_timer\>/qemu_new_timer_ns/' \
        $(git grep -l 'qemu_new_timer\>' )

after checking that get_clock and new_timer never occur twice
on the same line.  There were no missed occurrences; however, even
if there had been, they would have been caught by the compiler.

There was exactly one false positive in qemu_run_timers:

     -    current_time = qemu_get_clock (clock);
     +    current_time = qemu_get_clock_ns (clock);

which is of course not in this patch.

Amit Shah 127338e610 char: rename qemu_chr_reset to qemu_chr_generic_open
This function sends out the OPENED event to backends that
have drive the chardevs. The 'reset' is now a historical
artifact and we can now just call the function for what it
is.

Stefan Weil 6693665ace Fix SDL include path.
SDL header files can be included in two different ways:

* like this: #include <SDL/SDL.h>
* like this: #include <SDL.h>

The 1st alternative is simple and works in many cases.

The 2nd alternative needs sdl-config to get the
correct compiler flags. It is the recommended way
to write SDL includes and standard for QEMU.

The patch fixes two non-standard SDL includes.
