AOSP: Standarize on VFS_CAP_REVISION_2
In https://github.com/torvalds/linux/commit/8db6c34f1dbc8 , namespaced
file capabilities were introduced. That change updated VFS_CAP_REVISION
from VFS_CAP_REVISION_2 to VFS_CAP_REVISION_3.
Android code is written assuming v2 capabilities, and the code will
break if we naively try to treat a v2 structure as a v3 structure.
So don't even try.
Android kernels prior to v4.14 will not support this extended capability
structure, so attempting to set such capabilities will ultimately fail.
With 8db6c34f1dbc8, it appears that attempting to read a v3 capabilities
xattr will always downgrade the capability to a v2 capability, so it
really doesn't make sense to look for a v3 capability.
Android capabilities are only created at /system and /vendor filesystem
creation time by host tools. Android processes, within or outside a
namespace, are not permitted CAP_SETFCAP
(https://android-review.googlesource.com/c/platform/system/sepolicy/+/547801/1/public/domain.te
line 1101). So we should never have to deal with a v3 capability other
than those that might appear on the /system / /vendor partition at a
future date by a future author.

it can't be freshly checked. So if the time when the file system was

tune2fs: don't recover journal if device is busy.
tune2fs currently replays the journal if it needs
recovery and the filesystem isn't mounted.
The test for "is the filesystem mounted" isn't completely robust.
Lustre makes use of ext4 filesystems in a way that they are mounted
without being visible in /proc/mounts or similar.
This usage can easily be detected by attempting to open the device
with O_EXCL. tune2fs already does this and the EXT2_MF_BUSY flag
is set if open(O_EXCL) fails.
Several uses other than lustre mounts could cause O_EXCL to fail,
but in any case it seems unwise to recover the journal when something
else is keeping the device busy.
So add an extra test to avoid journal recovery when the device
is busy. This fixes some problems with lustre usage.

debian: remove -dbg packages from the control file
It looks like Debian's upload automation will reject a control file

build profiles will *disable* packages, but not *add* new binary
packages not normally built.)
So move the offending lines into debian/control.legacy-dbg which is
tacked onto the debian/control file via "./debian/rules debian-files"

debian: convert to use build profile rules exclusively
This commit drops support for the debian/rules.custom file, and only
relies on build profiles.
This means we no longer need to build the control file from
control.in, which simplifies this; developers can now build a debian
package immediately after checking out the tree from git. This also
implies that we are dropping support for Debian 7 (wheezy) and Ubuntu
Trusty (14.04LTS) and older releases. (People who want to backport to
these older distributions will have to make manual adjustments to the
debian/control and debian/rules files.)
Instead of using SKIP_E2FSCK_STATIC in debian/rules.custom, use the
new build profile: pkg.e2fsprogs.no-static-e2fsck
Support for the old-style *-dbg files used in Debian Jessie (which did
not support dbgsym packages) is completely automated. The system will
auto-detect systems which do not support dbgsym and automatically set
the pkg.e2fsprogs.legacy-pkg build profile.
