Mimi Zohar f381c27222 integrity: move ima inode integrity data management
Move the inode integrity data(iint) management up to the integrity directory
in order to share the iint among the different integrity models.

Changelog:
- don't define MAX_DIGEST_SIZE
- rename several globally visible 'ima_' prefixed functions, structs,
  locks, etc to 'integrity_'
- replace '20' with SHA1_DIGEST_SIZE
- reflect location change in appropriate Kconfig and Makefiles
- remove unnecessary initialization of iint_initialized to 0
- rebased on current ima_iint.c
- define integrity_iint_store/lock as static

There should be no other functional changes.

The Trusted Computing Group(TCG) runtime Integrity
Measurement Architecture(IMA) maintains a list of hash
values of executables and other sensitive system files,
as they are read or executed. If an attacker manages
to change the contents of an important system file
being measured, we can tell.
If your system has a TPM chip, then IMA also maintains
an aggregate integrity value over this list inside the
TPM hardware, so that the TPM can prove to a third party
whether or not critical system files have been modified.
Read <http://www.usenix.org/events/sec04/tech/sailer.html>
to learn more about IMA.
If unsure, say N.

IMA_MEASURE_PCR_IDX determines the TPM PCR register index
that IMA uses to maintain the integrity aggregate of the
measurement list. If unsure, use the default 10.
config IMA_AUDIT
bool
depends on IMA
default y
help
This option adds a kernel parameter 'ima_audit', which
allows informational auditing messages to be enabled
at boot. If this option is selected, informational integrity
auditing messages can be enabled with 'ima_audit=1' on
the kernel command line.
config IMA_LSM_RULES
bool
depends on IMA && AUDIT && (SECURITY_SELINUX || SECURITY_SMACK)
default y
help
Disabling this option will disregard LSM based policy rules.
