scripts: signall.sh store usign.key as usign.sec
The signall.sh script signs all files inside a tar via GPG and
signify-openbsd (similar to usign)e and attaches the signatures to the
same archive.
Using more recent versions of signify-openbsd requires a specific naming
schema for keys, private ending with .sec and public with .pub. This was
introduced at
763e1148f68f03cb2fa85d022500acf8c66af222[0].
This patch renames the stored key as usign.sec instead of usign.key. As
of the temporary nature of the key storing, this very unlikely breaks
any existing setups.

phase1: use buildinfo instead of prepare
Prepare target is used to compile tools and toolchain, however buildbot
only uses it to create the buildinfo files. This[0] PR splits prepare
and buildinfo allowing the buildbots to run the buildinfo creation only.
This should also fix the current issue with missing json info files:
prepare runs `target/compile` which removes all existing json info files
via `Device/Build`. Only `target/install` creates them via
`Device/Build/image`. However currently the buildbots run
`target/install` before (the second) `target/compile`.

750174c0cee95925dd322f37c211577d0ebc0dc4 attempted to inject ccache
into the CC environment, but that doesn't work as the CC/CXX variables
are processed by the build system, in order to extract the path to an
executable file.
This commit works around that situation by creating two simple wrapper
scripts on the slave. The remaining logic is unchanged:
When tryccache is False, CC/CXX point to the regular compilers and no
ccache injection is performed.
When tryccache is True, CC/CXX point to their respective wrapper, and
CCACHE is set to the path to ccache (if it exists, empty otherwise),
CCC/CCXX point to the original compilers, and the wrappers will execute
'${CCACHE} ${CCC} "$@"' or '${CCACHE} ${CCXX} "$@"'. If ${CCACHE} is
unset, this falls back to plain compilers.
i.e. ccache is only used if tryccache=True AND ccache has been found on
the slave.
Use 'exec' to avoid lingering shell during execution.

phase1: use do_cleanup to select Git() method
Git() parameters cannot accept a renderer such as Interpolate() (this
feature is only available from buildbot version 0.8.10).
To implement this feature in 0.8.9 we have to split the 'fresh' and
'clean' cases and make them separate steps that are mutually exclusive
(via doStepIf).

phase1: do not exceed nproc build concurrency
Contrary to popular belief, exceeding the number of available CPU cores
in parallel builds (by running e.g. 'make -j$(($nproc+1))' where 'nproc'
is the number of active CPUs on the system) brings no performance benefit,
and may in fact negatively affect build times. This performance hit can
be further aggravated by the extra memory pressure resulting from the
extraneous jobs.
See:
- https://blog.regehr.org/archives/1416
- http://blog.stuffedcow.net/2011/08/hyperthreading-performance/
This is particularly relevant in two distinct cases:
- on hyper-threaded systems, where half of the active CPUs are separate
threads on the same physical core;
- on virtualized guests systems, where the host physical CPUs are already
affected by system overhead not visible to the guest.

phase1: don't enable rsync compression where unnecessary
Enabling rsync compression for already compressed files adds CPU
and memory overhead that negatively impacts upload speed on data
that cannot be further compressed.
By default rsync ignores '-z' on a number of files it knows to be
already compressed (based on filename suffix), but the list is not
exhaustive and doesn't include e.g. '.ipk'. Instead of trying to maintain
a list of all known compressed suffixes uploaded by the build system,
it's simpler and less error prone to simply disable the option for
specific steps where all or nearly all of the transferred files are known
to be already compressed.

phase1: reduce verbosity of rsync
The purpose of this patch is to reduce uplink bandwidth contention when
rsync uploads are running.
This patch:
- replaces '-v' and '--progress' by '--info=name' in rsync's parameter
list (assuming it's necessary to output a list of updated files)
- introduces a wrapper script 'rsync.sh' which checks for the presence
and executability of 'pv' and pipes the output of rsync through
'pv -t -i 60 -f' if possible, and falls back to plain rsync otherwise.
'--info=name' prints one line to stdout for each file that is updated on
the remote side.
'pv -t -i 60 -f' prints a 1mn-resolution timer to stderr, with the goal
of preventing the current buildbot step to timeout due to lack of process
output.
It's worth noting that '--progress' did not prevent some timeouts (most
notably on the 'sourceupload' step) since --progress only emits output
for files that are updated on the remote side.

phase1: rsync: use --size-only instead of --checksum
'--checksum' puts heavy I/O and memory load on both the sender and the
receiver and dramatically reduces rsync's speedup. Furthermore, if
multiple slaves are uploading at once the receiver may become overloaded,
slowing down the whole build farm. From rsync manpage:
Generating the checksums means that both sides will expend a lot of
disk I/O reading all the data in the files in the transfer (and this
is prior to any reading that will be done to transfer changed files),
so this can slow things down significantly.
This slowdown causes timeouts for some build slaves, noticeably in the
'sourceupload' step.
'--size-only' matches files by size only. Compared to '--checksum', it is
faster, and does not aggravate the collision/error risk (if two files of
the same name and size have different checksums, we don't have a heuristic
to determine which is "correct" and which is "invalid" anyway)

phase1: provide upload/download locking
This patch offers an optional locking mechanism to ensure that specific
build slaves do not perform concurrent network operations
Each slave definition can feature two additional options:
ul_lock = <lock identifier string>
dl_lock = <lock identifier string>
In the scenario where a group of build slaves share the same physical
network link, these variables can be used as follows:
If the link is full duplex capable, each slave from the target group
would be configured with e.g.:
dl_lock = slavegroup1_dl
ul_lock = slavegroup1_ul
This enables separate locks for uplink and downlink.
If the link is not full duplex capable, then each slave from the target
group would be configured with e.g.:
dl_lock = slavegroup1
ul_lock = slavegroup1
Effectively making uplink and downlink share the same lock
If neither option is set, no lock is enforced and the patch is a no-op.
In this patch the locks are only applied to steps that cause significant
network traffic.
