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.

Upstream pull request #353: Add support for ATmega328PB.
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.

Handle writing a one bit to the interrupt flag, ADIF.
Link libsimavr.so with needed libraries. That is the usual way and allows
it to be easily loaded by dlopen().
Add a test for basic port functions and fix problems found.
avr_extint.c: prevent spurious interrupts.
avr_ioport.c: allow calling program to control value read from PIN.
Add casts to suppress warnings from gcc 8.3.0.
Implement the BIN and IPR bits for attinyX5 and change the ADC sample timing
to roughly match the datasheet. Add a test. Those MCUs have no UART, so
test.c and test.h have changes to use an alternative method.

Remove kludge "avr_uart_regbit_clear" from uart
modified: sim/avr_uart.c
Change use of kludge function avr_uart_regbit_clear to avr_regbit_clear.

Add check that avr_regbit_clear was passed a valid existing register.
Formatting and style corrections to avr_regbit.h
Set udre flag when (re)enabling uart transmitter.
modified: sim/avr_uart.c
Previously, disabling the uart transmitter cleared the udrc
interrupt and cleared the udre (udrc.raised) flag. Upon
reenabling the transmitter, the udre flag is still clear
signifying the buffer is full, thus waiting for the udr to
clear via udre flag hangs.
Test-related maintenance
- Ensure that make reports an error if any of the tests fail
- Don't duplicate compilation commands only for the sake of
verbosity control
- Simplify recipe for .tst files
- Drop outdated and unnecessary .gitignore from tests directory
- Add the execution of tests to Travis CI
Add support for non-auto release to button
This allows better control of key press length, if needed.
To minimize negative effect on existng code, if the duration
argument of button_press is non-zero, functionality is kept as is
(i.e., using auto-release). If duration is set to zero, then button
will have to be explicitly released using a new API function,
button_release.
If simulation uses GLUT, it may make use of glutKeyboardUpFunc and
glutIgnoreKeyRepeat (in addition to glutKeyboardFunc found in
existing examples) to have more exact control over button presses
and releases.

Update/fix manual
- Updated GitHub repository links.
- Removed the requirement for a German babel language definition

- Commented out missing references (citations of external manual

git disregard temporary latex files.
