77fead5b8a Fix more AddressSanitizer violations in usr.bin/top
In line_update(), set lastcol correctly after moving to any non-zero
column, so the "overwrite old stuff" part does not attempt to address
negative offsets in the current line.

Rewrite setup_buffer() to always allocate at least 80 characters,
otherwise various calls to summary_format() will overwrite the end of
the buffers, if the screen width gets small enough.

UINT64_MAX] range, and supports fast insert, predicated clearing of
subrange, and lookup of an interval containing the specified address.
Internally it is a pctrie over the interval start addresses.

Implementation provides additional guarantees over the structure state

a960df88d0 calendar: use iconv to respect the output encoding
calendar(1) can have input in various encoding, specifying
LANG=<locale_name> to enable calendar(1) to determine which one to use.

The problem is the content of the calendar itself is exposed as is making it
unreadable in many cases. For example french calendar which is encoded
ISO8859-1 is rendered badly in a fr_FR.UTF-8 environment.

Using iconv allows to solve this issue.
This will also allow to keep only 1 encoding in base for those files without
breaking user existing setup

9ac51119a8 Fix the handling of legacy-format devices in the u-boot loaderdev variable.
When I added support for the standard loader(8) disk0s2a: type formats,
the parsing of legacy format was broken because it also contains a colon,
but it comes before the slice and partition. That would cause disk_parsedev()
to return success with the slice and partition set to wildcard values.

This change examines the string first, and if it contains spaces, dots, or
a colon at any position other than the end, it must be a legacy-format
string and we don't even try to use disk_parsedev() on it.

bb4b140d4f Fix hangs in r341810 waiting for AP startup.
idle_td is dereferenced without thread-locking it to make its contents is
invariant, and was accessed without telling the compiler that its contents
is invariant.  Some compilers optimized accesses to the supposedly invariant
contents by moving the critical checks for changes outside of the loop that
waits for changes.  Fix this using atomic ops.

This bug only showed up for the following configuration: a Turion2
system, amd64 kernels, compiled by gcc, and SCHED_4BSD.  clang fails
to do the optimization with all CFLAGS that I tried, because it doesn't
fully optimize the '__asm __volatile' for cpu_spinwait() although this
asm has no memory clobber.  gcc only does the optimization with most
CFLAGS.  I mostly used -Os with all compilers.  i386 works because gcc
-m32 -Os only moves 1 or the 2 accesses outside of the loop.
Non-Turion2 systems and SCHED_ULE worked due to different timing (when
all APs start before the BP checks them outside of the loop).

c40618cd08 The way ZFS searches for its vdevs is the following: first it looks for
a vdev that has the same name as the one stored in metadata and that has
all VDEV labels in place. If it cannot find a GEOM provider with the given
name and all VDEV labels it will scan all GEOM providers for the best match
(the most VDEV labels available), but here the name is ignored.

In case the ZFS pool is created, eg. using GPT partition label:

	# zpool create tank /dev/gpt/tank

everything works, and on every import ZFS will pick /dev/gpt/tank and
not /dev/da0p4.

The problem occurs when da0p4 is extended and ZFS is unable to find all
VDEV labels in /dev/gpt/tank anymore (the VDEV labels stored at the end
of the partition are now somewhere else). In this case it will scan all
GEOM providers and will pick the first one with the best match, ie. da0p4.

Fix this problem by checking the VDEV/provider name even if we get the same
match. If the name is the same as the one we have in pool's metadata, prefer
this GEOM provider.

2b83f8a713 Make server_cat(..) handle short receives
In short, the prior code was far too simplistic when it came to calling recv(2)
and failed intermittently (or in the case of Jenkins, deterministically).

Handle short recv(2)s by checking the return code and incrementing the window
into the buffer by the number of received bytes. If the number of received
bytes <= 0, then bail out of the loop, and test the total number of received
bytes vs the expected number of bytes sent for equality, and base whether or
not the test passes/fails on that fact.

Remove the expected failure, now that the hdtr testcases deterministically pass
on my host after this change [1].

4207ba4fed Place an upper bound on the number of iterations for REP.
Right now it's possible to invoke the REP escape sequence with a maximum
of tens of millions of iterations. In practice, there is never any need
to do this. Calling it more frequently than the number of cells in the
terminal hardly makes any sense. By placing a limit on it, we can
prevent users from exhausting resources in inside the terminal emulator.

As support for this escape sequence is not present in any of the stable
branches, there is no need to MFC.

0a9182f1aa Limit the number of entries allocated for a REPORT_ZONES command.
The DIOCGETZONE ioctl can be used to fetch the zone list of an SMR
drive, and the caller specifies the number of entries it wants to fetch.
Clamp the caller's request to a sane limit so that a user cannot attempt
large allocations. Callers already need to invoke the ioctl multiple
times to fetch the full list in general, so there's no harm in limiting
the number of entries returned.

Fix style while here.
