c96050f43e qapi/crypto: Rename QCryptoRSAPaddingAlgorithm to *Algo, and drop prefix
QAPI's 'prefix' feature can make the connection between enumeration
type and its constants less than obvious.  It's best used with
restraint.

QCryptoRSAPaddingAlgorithm has a 'prefix' that overrides the generated
enumeration constants' prefix to QCRYPTO_RSA_PADDING_ALG.

We could simply drop 'prefix', but then the prefix becomes
QCRYPTO_RSA_PADDING_ALGORITHM, which is rather long.

We could additionally rename the type to QCryptoRSAPaddingAlg, but I
think the abbreviation "alg" is less than clear.

Rename the type to QCryptoRSAPaddingAlgo instead.  The prefix becomes
QCRYPTO_RSA_PADDING_ALGO.

7ba7db9fa1 migration/xbzrle: Use i386 host/cpuinfo.h
Perform the function selection once, and only if CONFIG_AVX512_OPT
is enabled.  Centralize the selection to xbzrle.c, instead of
spreading the init across 3 files.

Remove xbzrle-bench.c.  The benefit of being able to benchmark
the different implementations is less important than not peeking
into the internals of the implementation.

e3feb2cc22 util: import GTree as QTree
The only reason to add this implementation is to control the memory allocator
used. Some users (e.g. TCG) cannot work reliably in multi-threaded
environments (e.g. forking in user-mode) with GTree's allocator, GSlice.
See https://gitlab.com/qemu-project/qemu/-/issues/285 for details.

Importing GTree is a temporary workaround until GTree migrates away
from GSlice.

This implementation is identical to that in glib v2.75.0, except that
we don't import recent additions to the API nor deprecated API calls,
none of which are used in QEMU.

I've imported tests from glib and added a benchmark just to
make sure that performance is similar. Note: it cannot be identical
because (1) we are not using GSlice, (2) we use different compilation flags
(e.g. -fPIC) and (3) we're linking statically.

66997c42e0 cleanup: Tweak and re-run return_directly.cocci
Tweak the semantic patch to drop redundant parenthesis around the
return expression.

Coccinelle drops a comment in hw/rdma/vmw/pvrdma_cmd.c; restored
manually.

Coccinelle messes up vmdk_co_create(), not sure why.  Change dropped,
will be done manually in the next commit.

Line breaks in target/avr/cpu.h and hw/rdma/vmw/pvrdma_cmd.c tidied up
manually.

Whitespace in tools/virtiofsd/fuse_lowlevel.c tidied up manually.

checkpatch.pl complains "return of an errno should typically be -ve"
two times for hw/9pfs/9p-synth.c.  Preexisting, the patch merely makes
it visible to checkpatch.pl.
