The `nonnull' attribute specifies that some function parameters should be
non-null pointers. This is very useful as it helps the compiler generate
warnings on suspicious code and can also enable some small optimizations.
Also start using 'alloc_size' attribute in the allocator functions.
This is an initial step to better integrate our libc with the compiler:
these attributes are fully supported by clang and they are also useful
for the static analyzer.
Note that due to some bogus internal procedure in the way gcc ports
are built they may require updating if they were built before r280801.

I .. stupidly added code to return HAL_ANI_STATS to HAL_DIAG_ANI_STATS.
I discovered this in a noisy environment when the returned values were
enough to .. well, make everything terrible.
So - restore functionality.
Tested:
* AR5416 (uses the AR5212 HAL), in a /very/ noisy 2GHz environment.
Enough to trigger ANI to get upset and generate useful data.
The MAC addresses were totally wrong. They're like the DIR-625C1 - at
0x1ffe0004 and 0x1ffe0018. They're however stored as text strings.
The ath0 MAC address is also not set, even though the calibration
partition is valid.
So, pick the board address / first MAC as the ath0 MAC, and derive
arge0/arge1 from that. That way they're hopefully unique enough
for people with multiple devices.
Tested:
* DIR-655A1
TODO:
* Do the same for the DIR-625A1 and DIR-625C1.
So far, we were always using HID_USAGE() to determine the Usage ID of a
certain HID report input item. This does not work as intended if a field
is an array and the allowed usages are specified with a usage range, as
HID_USAGE() will return 0. We need to use the field value as an index in
the usage range list in this case instead.
This makes the volume keys in a Microsoft Bluetooth Mobile Keyboard
5000 be properly recognized. The relevant part of the HID report looks
like this:
0xA1, 0x01, // Collection (Application)
0x85, 0x07, // Report ID (7)
0x05, 0x0C, // Usage Page (Consumer)
0x19, 0x00, // Usage Minimum (Unassigned)
0x2A, 0xFF, 0x03, // Usage Maximum (0x03FF)
0x95, 0x01, // Report Count (1)
0x75, 0x10, // Report Size (16)
0x15, 0x00, // Logical Minimum (0)
0x27, 0xFF, 0x03, 0x00, 0x00, // Logical Maximum (1023)
0x81, 0x00, // Input (Data,Array,Abs,No Wrap,Linear,Preferred
// State,No Null Position)
When a key such as "volume down" is pressed, the following data is
transferred through Interrupt In:
0x07 0xEA 0x00

These are similar to the mips24k performance counters - some are
available on perfcnt0/3, some are available on perfcnt1/4.
However, the events aren't all the same.
* Add the events, named the same as from Linux oprofile.
* Verify they're the same as "MIPS32(R) 74KTM Processor Core Family
Software User's Manual"; Document Number: MD00519; Revision 01.05.
* Rename INSTRUCTIONS to something else, so it doesn't clash with
the alias INSTRUCTIONS. I'll try to tidy this up later; there
are a few other aliases to add and shuffle around.
Tested:
* QCA9558 SoC (AP135 board) - MIPS74Kc core (no FPU.)
* make universe; where it didn't fail for other reasons.
TODO:
* It'd be nice to support the four performance counters
in at least this hardware, rather than just two.

Summary:
Book-E and AIM trap.c are almost identical, except for a few bits. This is step
1 in unifying them.
This also renumbers EXC_DEBUG, to not conflict with AIM vector numbers. Since
this is the only one thus far that is used in the switch statement in trap(),
it's the only one renumbered. If others get added to the switch, which conflict
with AIM numbers, they should also be renumbered.
