Add missing header file to 'sim_hex.h'
'size_t' is not defined in any of the header files included in
'sim_hex.h', even though it is used in there.
You can see a list of all headers that define 'size_t' here
http://en.cppreference.com/w/c/types/size_t
parts: Move font.h for hd44780 display to parts directory
This file is referenced only by hd44780_glut.c in the parts folder,
so move it there and give it a prefix.
misc: Strip off tag prefix from the pkg-config version
For example, before this change the version would
be set as 'tag:v1.5'. After this change it will be
'v1.5'.
cores: Add support for Analog Comparator
timer: Added an IRQ for input capture trigger (ICP)

vcd: Extensive update; added support for VCD Input
Massive update here. Now allow reading from a VCD file, as long as the
traces are named in a way that allows us to connect an IRQ. Typically,
you can send pin values to for example PORTB5 by naming the trace
'iogB_5' -- you can use sigrock for example to capture traces from
real hardware, and 'replay' it in simavr.
Also since I was there, reworked the whole module to use a 'proper' FIFO
and simplified the output generation too.
There are a few 'TODO' left, but it's functional.

cores: Add a field for Lock Bits and Boot Lock Bits
Add an extra byte for allowing simavr store the chip's lock bits / boot
lock bits as well as set the default value as defined in a number of
specs.
cores: Fix fuse support to handle proper byte size
avr-libc specifies platforms with only 6, 3, 2, 1, and 0 bytes of fuses.
Previously simavr only had 4 bytes available for fuses and assumed any
platform using the CORE_DECLARE macro would have 3 fuses. This change
allows the CORE_DECLARE macro to support any of the platforms supported
by avr-libc with regard to fuses. Additionally add some defines to make
it clear for users of simavr what order the fuses are in.
