instead of having one simple per-file cache implement an more
comprehensive one that works for multiple files and can actually
maintain multiple maps per file and per object type.
In some cases, like wrong configuration, restarting after error
does not help, so administrator can specify statuses by RestartPreventExitStatus
which will not cause restart of a service.
Sometimes you have non-standart exit status, so this can be specified
by SuccessfulExitStatus.
This adds forward-secure authentication of journal files. This patch
includes key generation as well as tagging of journal files,
Verification of journal files will be added in a later patch.
- don't use pivot_root() anymore, just reuse root hierarchy
- first create all mounts, then mark them read-only so that we get the
right behaviour when people want writable mounts inside of
read-only mounts
- don't pass invalid combinations of MS_ constants to the kernel
The kernel does not allow switching roots if things are mounted
MS_SHARED. As a work-around, remount things MS_PRIVATE before switching
roots.
This should be fixed in the kernel for good.

Avoids compiler warning:
src/shared/utf8.c: In function 'ascii_filter':
src/shared/utf8.c:278:16: warning: assignment discards 'const' qualifier
from pointer target type [enabled by default]
Because root is now recursively marked as shared on bootup, we need to
recursively mark root as private. This prevents a pivot_root failure on
shutdown:
Cannot finalize remaining file systems and devices, giving up.
pivot failed: Invalid argument
Currently MIPS and ARM define syscall numbers for multiple ABI in one
<asm/unistd.h>. The #define statments for each syscall are formated as:
#define __NR_scname (BASE_OFFSET + sc_number)
Thus we need a more generic regular expression to match these in awk.
