regex(3): Handle invalid {} constructs consistently and adjust tests
Currently, regex(3) exhibits the following wrong behavior as demonstrated
with sed:
- echo "a{1,2,3}b" | sed -r "s/{/_/" (1)
- echo "a{1,2,3}b" | sed "s/\}/_/" (2)
- echo "a{1,2,3}b" | sed -r "s/{}/_/" (3)
Cases (1) and (3) should throw errors but they actually succeed, and (2)
throws an error when it should match the literal '}'. The correct behavior
was decided by comparing to the behavior with the equivalent BRE (1)(3) or
ERE (2) and consulting POSIX, along with some reasonable evaluation.
pgrep naively appends the delimiter to all PIDs including the last
e.g. "pgrep -d, getty" outputs "1399,1386,1309,1308,1307,1306,1305,1302,"
Ensure the list is correctly delimited by suppressing the emission of the
delimiter after the final PID.

- If available, use TRIM instead of ERASE for implementing BIO_DELETE.
This also involves adding a quirk table as TRIM is broken for some
Kingston eMMC devices, though. Compared to ERASE (declared "legacy"
in the eMMC specification v5.1), TRIM has the advantage of operating
on write sectors rather than on erase sectors, which typically are
of a much larger size. Thus, employing TRIM, we don't need to fiddle
with coalescing BIO_DELETE requests that are also of (write) sector
units into erase sectors, which might not even add up in all cases.
- For some SanDisk iNAND devices, the CMD38 argument, e. g. ERASE,
TRIM etc., has to be specified via EXT_CSD[113], which now is also
handled via a quirk.
- My initial understanding was that for eMMC partitions, the granularity
should be used as erase sector size, e. g. 128 KB for boot partitions.
However, rereading the relevant parts of the eMMC specification v5.1,
this isn't actually correct. So drop the code which used partition
granularities for delmaxsize and stripesize. For the most part, this
change is a NOP, though, because a) for ERASE, mmcsd_delete() used
the erase sector size unconditionally for all partitions anyway and
b) g_disk_limit() doesn't actually take the stripesize into account.
- Take some more advantage of mmcsd_errmsg() in mmcsd(4) for making
error codes human readable.

Expose API to allow disks to ask for alias names in devfs.
Implement disk_add_alias to allow aliases to be added to disks. All
disk have a primary name (say "foo") can also have secondary names
(say "bar") such that all instances of "foo" also have a "bar"
alias. So if you have foo0, foo0p1, foo1, foo1s1 and foo1s1a nodes
created by the foo driver and gpart, device nodes bar0, bar0p1, bar1,
bar1s1 and bar1s1a will appear as symlinks back to the original nodes.
This generalizes to multiple aliases. However, since the unit number
follows the primary name, multiple device drivers can't create the
same aliases unless those drives coorinate the unit number space (eg
you couldn't add an alias 'disk' to both 'da' and 'ada' because it's
possible to have da0 and ada0, because 'disk0' is ambiguous).

6 11 12 13 14 15 16 17 18 19 20 7 8 9 10.
So the sequence of the bio's is damaged in the flush queue (and
therefore in the journal on disk !). This error can be triggered by
ffs_snapshot() when a block is read with readblock() and gjournal finds
this block in the broken flush queue before it goes to the correct
active queue.
The fix is to place all new blocks at the end of the queue.

My change had good intentions, but the implementation was incorrect:
- printf was returning the number of characters in the format string
plus the NUL, but failed in two regards implementation wise:
-- the pathological case, printf(""), wasn't being handled properly since
the pointer is always incremented, so the value returned would be
off-by-one.
-- printf(3) reports the number of characters printed post-conversion via
vfprintf, etc.
- putchar(3) should return the character printed or EOF, not the number
of characters output to the screen.
My goal in making the change (again) was to increase parity, but as bde
pointed out these are freestanding functions, so they don't have to
conform to libc/POSIX. I argued that the functions should be named
differently since the implementation is different enough to warrant it
and to allow boot2 code to be usable when linked against sys/boot and
libstand and other libraries in base. I have no interest in pushing
