This affects GNU make in particular, which can otherwise receive SIGCHLD during
vfork(), fail to deliver it, and subsequently miss all future SIGCHLDs due to
signal deduplication.

This allows "remote" locking of ThreadGroup.signalHandlers.mu without needing
to lock TaskSet.mu, analogously to Linux's lock_task_sighand().
This reveals a bug: kernel.Task.sendSignal[Timer]Locked() unintentionally
requires TaskSet.mu to be locked since it reads Task.exitState. To fix this,
use atomic memory operations on Task.exitState when required.

- Add Kernel.IsPaused() which indicates whether the kernel is currently paused.
- Add TaskSet.ForEachThreadGroup() which allows callers to iterate through all
thread groups in the kernel.
- Export FDTable.ForEach() which allows other packages to iterate over all FDs.

Our "Preconditions:" blocks are very useful to determine the input invariants,
but they are bit inconsistent throughout the codebase, which makes them harder
to read (particularly cases with 5+ conditions in a single paragraph).
I've reformatted all of the cases to fit in simple rules:
1. Cases with a single condition are placed on a single line.
2. Cases with multiple conditions are placed in a bulleted list.
This format has been added to the style guide.
I've also mentioned "Postconditions:", though those are much less frequently
used, and all uses already match this style.
