The smack_new_label_from_path function reads an xattr

isn't a label, so this function shouldn't be used to fetch

d7319c71 introduced an internal function for opening smackfs files,
when there is a long and short label version. The new function always
opens the file write only, but smack_have access() requires O_RDWR.
The internal function is now extended to take argument with file access
mode.

libsmack: add function for policy loading at system startup
New function smack_load_policy() is intended to be used by systemd for
policy loading at system startup. It reuses existing code from

libsmack: add functions for setting and removing labels on files
Jóse Bollo implemented two functions as part of this various
improvements for the chsmack command-line utility:
- smack_set_label_for_path() (see f1dfd85)
- smack_remove_label_for_path() (see 5da1a22)
Since they are generally useful, they should be part of the
API in libsmack 1.1.
This patch migrates these functions to libsmack and exports
the symbols. Also, the chsmack is modified to use the new API
instead of the internal functions.

libsmack: enable multi-line support for writing to load2 and change-rule
Since Linux 3.12 Smack can handle multiple rules in single write when
loading policy. Libsmack will detect this support and group rules into
blocks of PAGE_SIZE-1 bytes at most. This results in much smaller number
of syscalls and faster loading of large policy.

libsmack: merge rules with the same subject and object before applying them
All rules with the same subject and object will be merged into a single one
before applying rules to kernel or writing them to a file. The result will
consist of smaller number of rules, but they will have the same semantics.
This enhances performance greatly when there are a lot of rules to merge.
The merging code has negligible overhead when there are no merges to
perform.

libsmack: change semantics of rule allow_code and deny_code
Fields in struct smack_rule are used to store either set or modify rule.
Set rules used to be distinguished by having deny_code = -1.
It is more convenient to have it differently: allow_code describing bits
that are to be set, deny_code describing bits that are to be cleared.
With that semantics access_code = ~deny_code for set rules. This enables
easy replacement of change rules that can be simplified to a set rule.
Thanks José Bollo for original idea about simplifying modify rules.

libsmack: reorganize rule lists for struct smack_accesses
Until now rule list was implemented as single linked list of all rules
added into struct smack_accesses. This patch breaks this list into several
lists, with one list of rules per subject label.
Each element in array of labels describe single label and all rules when it's a
subject are added into this label's list.
This data structure is close to internal kernel data structures for Smack
rules. This allows for slightly better performance because rules are
grouped by subject.
More importantly though, this patch prepares ground for rule merging.
