Merge pull request #499 from gatk555/gdb_burst
Speed execution with GDB
Merge pull request #494 from gatk555/vcd_names
Fix duplicate VCD names.
Speed execution with GDB by running a burst of instructions before
checking for input from GDB. Discussed in #489.
Merge pull request #491 from gatk555/hex2
Combined function for loading ELF or ihex firmware.
Pull the .hex loading code out of run_avr.c and make it available as
a function, sim_setup_firmware(), that also handles ELF firmware.
Add a test, test_atmega88_hex.c, and use the new function in other tests.

Merge pull request #488 from gatk555/tiny13

Merge pull request #490 from gatk555/logging
Correct output streams for logging output.
Correct output streams for logging output.
Fix error in PR #482 that breaks build when tracing is enabled.
Use the Program Header Table to control loading from ELF files rather than
the Section Table. Fixes upstream #484 "Located sections are ignored
by simavr".
Cherry-pick
8fa3b206d917609ae696e4e9d89cfbec211113ff onto upstream.
Make the global interrupt pending IRQ behave consistently, so that the
value is always a vector number. Make the floating flag more useful;
when set it indicates the next interrupt expected. Remove a call
that added no information. Add a test.

Gdb: add support for "load" and "info_registers" and fix bugs.
Really fix handling of 'break' (testing blunder) and include
a helpful message when it is executed. Also add help message
response for gdb's "monitor" command.
Fix bugs in handling vFlashWrite in sim_gdb.c and reset the
cycle counter on reset so that there is no crash on restart.
Make the break instruction useful. The previous implementation
could never move past it, as gdb knows it is in ROM and will
not replace it. Distinguish hard and soft breaks.
Fix access (read/write) watchpoints and incorrect reporting of watchpoint
stops (always reported as "awatch"). Fix the kill command and allow
the simulator to continue running on detach.
Add "monitor say" for debugging.
Fix three problems with gdb support:
1. Do not report a TRAP signal on every stop, as it confuses gdb.
Initial symptom was failure to step into an ISR.
2. AVR was running after reset command.
3. Excessive processor activity (buzzing) while AVR stopped.
Support for gdb's "load" command, based on
https://github.com/msquirogac/simavr/tree/fix-371
This implements the vFlashxxxx remote protocol commands and should fix
issue #371 - "GDB Error on OS X: Remote target does not support flash erase".
Fix issue #478 - input changes not reflected in VCD output file.
Change the way I/O register IRQs are called so that they report
changes made by peripheral code as well as the core.
Also, do not call them for reads. Add some test code.
Minor improvements to VCD file input.
avr_adc.h: Remove space from ioctl name as it would break VCD parsing.
sim_vcd_file.*: Allow nano-second input timing, compatible with output.
Extend VCD parsing.
Fix bug in short-form parsing where variable alias is a digit.
Fix input bug with slow clock.
Ignore Visual Studio Code files.
Fix WDIE being wrongly cleared in Interrupt Mode
WDIE must be automatically cleared only in "Interrupt and System
Reset Mode" (where it's used to transition to "System Reset Mode").
In other modes, watchdog interrupt must not clear WDIE.
Strictly speaking, the modified condition also clears it in
"System Reset Mode" as well, but the system is reset on
interrupt anyway, so it doesn't matter.

Travis-ci:added support for ppc64le
Make the 2560 PORTE/0 pin change interrupt visible as it mostly works.
Add the missing pin change interrupts for 1280 and 1281.
In avr_ioport.[ch], fix multiple causes (but not all) of
mis-triggering of pin change interrupts including upstream issue #343:
Pin change interrupts incorrectly fire when a timer compare event occurs.
Other causes are initial setting of DDR and the AVR_IOPORT_OUTPUT bit.
Move the mask and shift data for ATmega2560 into the ioport structure.
Add a test for pin change interrupts.
Fixes for ATmega2560 and friend:
enable pin change interrupts on PORTK;
conditionally enable pin change interrupts on PORTE/0 - shared with PORTJ;
run the ACOMP initialisation function;
add close relative ATmega2561.

Patch offered in upstream issue #339 (from djfd):
Wrong ADC definition at-tiny-24
Do not set filter flag as handlers for IOPORT_IRQ_REG_PIN should be
called on every read of the port pins, so they can set new values.

it to be easily loaded by dlopen().
