lvm2: update to 2.03.42

LVM2 2.03.42:
- add --lockopt retries=N / removeretry=SECONDS to lvmlockd
- use lockd_lv lock probes for pvmove holder availability in shared VGs
- auto-revert metadata when initial pvmove mirror activation fails
- refuse activation of a pvmove-locked LV when pvmove runs on another
  node; allow pvmove --abort without args when using lvmlockd
- add cluster lock lifecycle for pvmove LV in shared VGs, and support
  for pvmove in a shared VG
- allow lvremove -f to remove pvmove-locked LVs after an interrupted
  pvmove; handle active pvmove during vgchange -an with force flags
- fix pvmove completion to use suspend+resume for DM table reload; fix
  deactivation cascade during active pvmove
- support inactive LVs in pvmove with metadata-only mirror insertion;
  kill orphaned polling process on pvmove --abort
- support formatting vdo volumes with the kernel vdo target (>=9.2);
  fix VDO index_memory_size_mb quantisation and report the minimum
  required pool size
- add --enable-asan/--enable-tsan build options

device-mapper 1.02.216:
- make libdm thread safe
- add use_kernel_format to dm_vdo_target_params
- introduce libdevmapper-san with --enable-asan/--enable-tsan
- parent table force reload when child device table changes

Refreshed 002-const-stdio.patch and 003-no-mallinfo.patch against the
new upstream source (make package/lvm2/refresh; hunk offsets only, no
content change) and gave both a proper git-am header block (From/Date/
Subject/Signed-off-by), crediting their original authorship (Daniel
Golle, 2015) with an accurate subject/body; they previously had none,
which the CI formality bot flagged. The header block was drafted via
git format-patch against a scratch commit of the pristine source, then
the whole patch re-refreshed through quilt so the diff body matches
what make package/lvm2/refresh actually produces byte for byte -
format-patch output alone does not survive OpenWrt's own refresh
(diff --git/index lines and full @@ context get stripped, the
trailing signature dropped), which is what the CI patch-format check
was rejecting before this.

+
+create_toolcontext()/destroy_toolcontext() tune glibc's stdio stream
+buffering directly via glibc-only internals; _check_standard_fds() has
+a musl-compatible fallback path already available. Wrap the
+glibc-specific code in #ifdef __GLIBC__ so this builds against musl.

+Subject: [PATCH] no-mallinfo: guard glibc mallinfo()/mlockall policy behind
+ __GLIBC__
+
+_allocate_memory()'s heap-growth probing uses glibc's MALLINFO/mallinfo(),
+which musl doesn't provide; guard it behind #ifdef __GLIBC__ and always
+grow by the full alloc_size on musl instead. Likewise _lock_mem() reads
+activation/use_mlockall from lvm.conf on glibc but always uses mlockall
+unconditionally on musl, where the glibc-specific heuristic this option
+tunes doesn't apply.
