Stefan Hajnoczi 91f32b0c92 qtest: Include system headers before user headers
It is dangerous to include user headers before system headers since user

Andreas Färber 2ad645d285 qtest: Use -display none by default
This avoids each test needing to add it to suppress windows popping up.

[Commit 7ceeedd016 ("blockdev-test: add
test case for drive_add duplicate IDs") and commit
43cd209803 ("qdev-monitor-test: add
device_add leak test cases") added qtest tests without specifying
-display none.

As a result, "make check" now tries to use graphics (GTK or SDL).  Since
graphics are not used by the test and inappropriate for headless "make
check" runs, add the missing -display none.

This fixes "make check" in the QEMU buildbot.

Paolo Bonzini 0d09e41a51 hw: move headers to include/
Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches.

Cole Robinson eeb29fb9aa rtc-test: Fix test failures with recent glib
As of glib 2.35.4, glib changed its logic for ordering test cases:

https://bugzilla.gnome.org/show_bug.cgi?id=694487

This was causing failures in rtc-test. Group the reordered test
cases into their own suite, which maintains the original ordering.

Alex Horn 02c6ccc6dd rtc: Only call rtc_set_cmos when Register B SET flag is disabled.
This bug occurs when the SET flag of Register B is enabled. When an RTC
data register (i.e. any of the ten time/calender CMOS bytes) is set, the
data is (as expected) correctly stored in the cmos_data array. However,
since the SET flag is enabled, the function rtc_set_time is not invoked.
As a result, the field base_rtc in RTCState remains uninitialized. This
causes a problem on subsequent writes which can end up overwriting data.
To see this, consider writing data to Register A after having written
data to any of the RTC data registers; the following figure illustrates
the call stack for the Register A write operation:

 +- cmos_io_port_write
 +-- check_update_timer
 +---- get_next_alarm
 +------ rtc_update_time

In rtc_update_time, get_guest_rtc calculates the wrong time and
overwrites the previously written RTC data register values.

Paolo Bonzini b8994faf2a rtc: implement century byte
Implement the century byte in the RTC emulation, and test that it works.
This leads to some annoying compatibility code because we need to treat
a value of 2000 for the base_year property as "use the century byte
properly" (which would be a value of 0).

The century byte will now be always-zero, rather than always-20,
for the MIPS Magnum machine whose base_year is 1980.  Commit 42fc73a
(Support epoch of 1980 in RTC emulation for MIPS Magnum, 2009-01-24)
correctly said:

    With an epoch of 1980 and a year of 2009, one could argue that [the
    century byte] should hold either 0, 1, 19 or 20.  NT 3.50 on MIPS
    does not read the century byte.

so I picked the simplest and most sensible implementation which is to
return 0 for 1980-2079, 1 for 2080-2179 and so on.

Paolo Bonzini b6db4aca20 rtc: fix overflow in mktimegm
When setting a date in 1980, Linux is actually disregarding the century
byte and setting the year to 2080.  This causes a year-2038 overflow
in mktimegm.  Fix this by doing the days-to-seconds computation in
64-bit math.
