tests/sys/file: add tests for the lowest fd after fork
fdcopy() skips plain kqueues and close-on-fork descriptors when it
copies the table into the child. Check that dup(2) in the child still
returns the lowest unused descriptor, both when the skipped descriptor
is the lowest free slot and when it sits above an existing hole.
Test cases:
kqueue_no_hole a plain kqueue is the lowest descriptor; the
child's dup() reuses its slot
kqueue_two two adjacent plain kqueues; the child's dup()
returns the lower one
kqueue_above_hole a plain kqueue sits above a closed descriptor;
the child's dup() returns the hole
kqueue_cponfork a KQUEUE_CPONFORK kqueue is copied; the child's
dup() returns the next slot
clofork_no_hole an O_CLOFORK descriptor is the lowest one; the
child's dup() reuses its slot

[libc] Return the written character from putc, fputc and putchar on baremetal and gpu (#240248)
Follow-up to #239980, which changed the generic implementations to
return the character written as an unsigned char converted to int, as C
requires, and updated the shared tests to expect it. The baremetal and
gpu implementations still returned zero.
Each of the six functions now returns `static_cast<int>(uc)` on success.

[CIR] Emit no-trapping-math and stack-protector-buffer-size function attribute (#234029)
Mirror classic codegen's `getDefaultFunctionAttributes` by setting
`"no-trapping-math"` (when FP exceptions are ignored) and
`"stack-protector-buffer-size"` on function definitions and
declarations. Both are lowered to LLVM IR through the `passthrough`
attribute array, since `llvm.func` has no dedicated fields for them.
Most changes are related to testing.

devel/got: update to 0.130.1
User-visible changes:
- default to using SHA256 object IDs in newly created repositories
The got-portable-0.130 release accidentally skipped some commits
from got 0.130.
(cherry picked from commit 734848d93cd26f5028d7fbc57e2d0b31a27bf9d2)
devel/got: Cherry-pick patches for shared locking
When operating on a worktree, got locks the tree in order to avoid
problems with concurrent operations. Until now, got always used
exclusive locks, which caused problems when e.g. two separate parts
of the FreeBSD release build ran 'got tree' at once.
This has been fixed upstream but the 15.2 release cycle needs the
changes urgently and can't wait for the next got-portable release,
so cherry-pick those patches.
