Subject: [PATCH] journal/compress: return early in uncompress_startswith
uncompress_startswith would always decode the whole stream, even
if it did not start with the given prefix.
Reallocation policy was also strange.

Subject: [PATCH] logind: allow switching to unused VTs via SwitchTo()
If compositors use the new SwitchTo() logic to map F1-F12, we should allow
them to switch to unregistered VTs, too. Otherwise, the auto-spawn logic
of gettys won't trigger.

Subject: [PATCH] journal/compress: improve xz compression performance
The new lzma2 compression options at the top of compress_blob_xz are
equivalent to using preset "0", exept for using a 1 MiB dictionary
(the same as preset "1"). This makes the memory usage at most 7.5 MiB
in the compressor, and 1 MiB in the decompressor, instead of the
previous 92 MiB in the compressor and 8 MiB in the decompressor.
According to test-compress-benchmark this commit makes XZ compression
20 times faster, with no increase in compressed data size.
Using more realistic test data (an ELF binary rather than repeating
ASCII letters 'a' through 'z' in order) it only provides a factor 10
speedup, and at a cost if a 10% increase in compressed data size.
But that is still a worthwhile trade-off.
According to test-compress-benchmark XZ compression is still 25 times
slower than LZ4, but the compressed data is one eighth the size.
Using more realistic test data XZ compression is only 18 times slower
than LZ4, and the compressed data is only one quarter the size.
