make(1): move test for recursive variable to cond-func-empty

Previously, the documentation of that test was much too short to explain
all the effects that happened in the bug situation from 2020-06-28 until
2020-07-02.

make(1): rename conflicting global variables called 'error'

When compiling make in all-in-one mode, these variable names conflict.
They could have been merged into a single variable, but that would have
required to make it a global variable for the other modules as well.
The parse module has a similar variable called 'fatals'.  All these can
possibly be merged into a single variable, but not now.

(rillig)

make(1): rename global variables in job.c

When compiling make in all-in-one mode, the variable name nfds conflicts
with the local variable name nfds in meta_compat_parent.

The variable name jobfds was misleading.  It has nothing to do with file
descriptors, it's just an array of jobs.

Improve detection of NS vs S views of priorities.

For PMR, write a 0 to bit7 and see if it sticks. This is only possible from
NS EL1 if we have a non-secure view of ICC_PMR_EL1.

For int priorities (GICD/GICR interfaces and LPIs), assume that the
GICD_CTLR.DS bit is telling us the truth.

RK3399 is special here when using the vendor bootloader, so keep the
auto-detection from the previous commit but limit the scope to only run
on RK3399 SOCs.

make(1): add high-level API for CandidateSearcher

This avoids passing invisible void pointers around in Lst_Append.  It

(rillig)

make(1): add CandidateSearcher to resolve transformation rules

Having a simple list of candidates is not enough.  It is currently
possible to construct endless loops with huge memory usage, as
demonstrated in suff-transform-endless.mk.

To fix this, a straight-forward idea is to remember which candidates
have already been searched and to not search them again.

This also fixes a small inconsistency in the code.  Most parameters had
been named slst (the s came from a time when Candidate was named Src),
except for Suff_FindDeps, where the variable was named srcs.  The
confusing thing about this was that the name srcs is used throughout the
file for a different purpose.  Only in FindThem there were two
parameters of the same type, which made this even more confusing.

code.

Fix interrupt priorities on N1 SDP.

The GICv3 architecture specification is not clear on the NS view of
priority registers, and there doesn't seem to be any consistency in how
these are implemented in both real and emulated environments.

The previous fix for this issue was meant to detect what we thought at the
time was a bug on the Rockchip RK3399. At that time the theory was somehow
EL1 has a secure view of the hardware, and this is causing us to have the
wrong view of IPRIORITYRn based on IHI0069F section 4.8.6 "Software
accesses of interrupt priority". But it turns out that this is not the
full picture. While I was able to confirm that yes, we do have secure
access to the GIC on RK3399 from EL1, the view of IPRIORITYRn differs
depending on whether you are using the Rockchip TF-A as included with
https://github.com/ayufan-rock64/linux-u-boot (shifted view), or mainline
TF-A from pkgsrc (unshifted view).

So to detect this quirk, we need three things: A method to detect if we
have S access to GIC registers, a method to see how many PMR bits are
implemented, and a method to see how many IPRIORITYRn bits are implemented.

To detect S access, we can try to toggle GICD_CTRL.EnableGrp1S. This bit
is either RES0 (security extensions not implemented), RAZ/WI (non-secure
access in two security state systems) or RW (secure access in two security
state systems).

To read the number of PMR and IPRIORITYRn bits supported, we can write all
1s to the register fields and read them back.

For the RK3399 (Rockchip TF-A) quirk, we assume a shifted view of
IPRIORITYRn if we have detected S accesses, and the PMR and IPRIORITYRn
values differ. The S access test is required because some real hardware
implementations (Ampere eMAG) were observed to report different PMR and
IPRIORITYRn masks, but present an unshifted view of IPRIORITYRn.

During testing, I also discovered that QEMU 5.1 requires this shifted view
workaround as well -- as far as I can tell, this is a QEMU bug. We can't
detect it the same way as RK3399 because security is disabled in the
emulated GIC, and the PMR and IPRIORITYRn tests both return 0xff! So now
if the GICv3 driver sees this configuration, it assumes that the shifted
view is required.

Honestly, this feature is so poorly documented that maybe it is better to
give up on HW priorities and preemption and use a single flat model like
Linux and FreeBSD does.

Tested on Arm N1 SDP, ROCKpro64 (RK3399) with Rockchip and pkgsrc TF-A,
Pinebook Pro (RK3399), Lenovo HR330A (Ampere eMAG), QEMU 5.1 (gic-version=3),
AWS EC2 a1.medium (Graviton).
