sched_ext: Maintain an online cid mask in the scheduler arenagrafted

Schedulers on the default cid mapping treat [0, nr_online_cids) as the
online set and restart on hotplug. Schedulers that install their own mapping
with scx_bpf_cid_override() have no way to learn which cids are online: the
count no longer identifies members and the CPU-form cpumask is unusable from
cid programs. This is an obvious hole in the cid API.

Add scx_bpf_online_cmask(), a kernel-maintained cmask in the scheduler's
arena, allocated alongside the per-CPU scratch masks and populated after the
cid mapping is finalized and before ops.init(), for child schedulers too.
The pointer stays valid through ops.exit() with no reference to take. It is
the arena offset as a void pointer, the same form struct_ops arena arguments
arrive in. The verifier types the void return as a scalar for the program's
arena cast.

The mask follows the SCX hotplug notifications: seeded from cpu_active_mask
and updated before ops.cid_online/offline() runs, so it lags cpu_online_mask
only inside a hotplug transition. Updates walk the scheduler list under the
lock that also serializes unlinking. Reads are live, not atomic snapshots.
Root initialization excludes hotplug.

+This file is intended to give you an overview of the default keys used
+by speakup for it's review functions.  You may change them to be
+anything you want but that will take some familiarity with key
+mapping.
+
+We have remapped the insert or zero key on the keypad to act as a
+shift key.  Well, actually as an altgr key.  So in the following list
+InsKeyPad-period means hold down the insert key like a shift key and
+hit the keypad period.
+
+KeyPad-8		Say current Line
+InsKeyPad-8		say from top of screen to reading cursor.
+KeyPad-7		Say Previous Line (UP one line)
+KeyPad-9		Say Next Line (down one line)
+KeyPad-5		Say Current Word
+InsKeyPad-5		Spell Current Word
+KeyPad-4		Say Previous Word (left one word)
+InsKeyPad-4		say from left edge of line to reading cursor.
+KeyPad-6		Say Next Word (right one word)
+InsKeyPad-6		Say from reading cursor to right edge of line.
+KeyPad-2		Say Current Letter
+InsKeyPad-2		say current letter phonetically
+KeyPad-1		Say Previous Character (left one letter)
+KeyPad-3		Say Next Character (right one letter)
+KeyPad-plus		Say Entire Screen
+InsKeyPad-plus		Say from reading cursor line to bottom of screen.
+KeyPad-Minus		Park reading cursor (toggle)
+InsKeyPad-minus		Say character hex and decimal value.
+KeyPad-period		Say Position (current line, position and console)
+InsKeyPad-period	say colour attributes of current position.
+InsKeyPad-9		Move reading cursor to top of screen (insert pgup)
+InsKeyPad-3		Move reading cursor to bottom of screen (insert pgdn)
+InsKeyPad-7		Move reading cursor to left edge of screen (insert home)
+InsKeyPad-1		Move reading cursor to right edge of screen (insert end)
+ControlKeyPad-1		Move reading cursor to last character on current line.
+KeyPad-Enter		Shut Up (until another key is hit) and sync reading cursor
+InsKeyPad-Enter		Shut Up (until toggled back on).
+InsKeyPad-star n<x|y>	go to line (y) or column (x). Where 'n' is any
+		allowed value for the row or column for your current screen.
+KeyPad-/		Mark and Cut screen region.
+InsKeyPad-/		Paste screen region into any console.
+
+Hitting any key while speakup is outputting speech will quiet the
+synth until it has caught up with what is being printed on the
+console.

+Speakup project home:  http://www.linux-speakup.org
+
+Mailing List:  speakup@linux-speakup.org
+
+Speakup is a kernel based screen review package for the linux operating
+system.  It allows blind users to interact with applications on the
+linux console by means of synthetic speech.
+
+Currently, speakup has one issue we know of.
+
+It seems to only happen on SMP systems. It seems that text in the output buffer
+gets garbled because a lock is not set. This bug happens regularly, but no one
+has been able to find a situation which produces it consistently.
+
+Patches, suggestions, corrections, etc, are definitely welcome.
+
+We prefer that you contact us on the mailing list; however, if you do
+not want to subscribe to a mailing list, send your email to all of the
+following:

+okash.khawaja@gmail.com, w.d.hubbs@gmail.com, chris@the-brannons.com,
