Ilya Leoshkevich 379652e967 tests/tcg: Don't #include <inttypes.h> in aarch64/system/vtimer.c
make check-tcg fails on Fedora with:

    vtimer.c:9:10: fatal error: inttypes.h: No such file or directory

Fedora has a minimal aarch64 cross-compiler, which satisfies the
configure checks, so it's chosen instead of the dockerized one.
There is no cross-version of inttypes.h, however.

Fix by using stdint.h instead. The test does not require anything
from inttypes.h anyway.

Peter Maydell 8d37a1425b target/arm: Handle overflow in calculation of next timer tick
In commit edac4d8a16 back in 2015 when we added support for
the virtual timer offset CNTVOFF_EL2, we didn't correctly update
the timer-recalculation code that figures out when the timer
interrupt is next going to change state. We got it wrong in
two ways:
 * for the 0->1 transition, we didn't notice that gt->cval + offset
   can overflow a uint64_t
 * for the 1->0 transition, we didn't notice that the transition
   might now happen before the count rolls over, if offset > count

In the former case, we end up trying to set the next interrupt
for a time in the past, which results in QEMU hanging as the
timer fires continuously.

In the latter case, we would fail to update the interrupt
status when we are supposed to.

Fix the calculations in both cases.

The test case is Alex Bennée's from the bug report, and tests
the 0->1 transition overflow case.

Paolo Bonzini bb52a8a278 tests/tcg: compile system emulation tests as freestanding
System emulation tests do not run in a hosted environment, since they
do not link with libc.  They should only use freestanding headers
(float.h, limits.h, stdarg.h, stddef.h, stdbool.h, stdint.h,
stdalign.h, stdnoreturn.h) and should be compiled with -ffreestanding
in order to use the compiler implementation of those headers
rather than the one in libc.

Some tests are using inttypes.h instead of stdint.h, so fix that.

Alex Bennée c00506aa26 gdbstub: implement a softmmu based test
This adds a new tests that allows us to test softmmu only features
including watchpoints. To do achieve this we need to:

  - add _exit: labels to the boot codes
  - write a memory.py test case
  - plumb the test case into the build system
  - tweak the run_test script to:
    - re-direct output when asked
    - use socket based connection for all tests
    - add a small pause before connection

Alex Bennée f6482872f3 tests/tcg/aarch64: add system boot.S
This provides the bootstrap and low level helper functions for an
aarch64 kernel. We use semihosting to handle test output and exiting
the emulation. semihosting's parameter passing is a little funky so we
end up using the stack and pointing to that as the parameter block.
