48d0cd3564 Misc cleanups in the new mlock code, incl. improving some variable names
& messages; using more statics (for now) to avoid redundant
recalculation; validating config file just once on loading; keeping maps
file open.

89f30d2df7 Unconditionaly ignore also Virtual Dynamically-linked Shared Object
(VDSO on 32bit is VSyscall on 64bit)
It seems it could be locked on 64bit kernels running 32bit binaries,
but it makes troubles on real 32bit machines where mlock() returns
error when trying to lock such map area. (0xffffe000)
Behavior of mlockall() seems to be similar.

0c897ecefd mlockall() -> mlock()
This patch adds a new implementation of locking function instead
of mlockall() that may lock way too much memory (>100MB).
New function instead uses mlock() system call and selectively locks
memory areas from /proc/self/maps trying to avoid locking areas
unused during lock-ed state.

Patch also adds struct cmd_context to all memlock() calls to have
access to configuration.

For backward compatibility functionality of mlockall()
is preserved with "activation/use_mlockall" flag.

As a simple check, locking and unlocking counts the amount of memory
and compares whether values are matching.

5451f79f55 This patch add SELINUX_LIBS and STATIC_LIBS variables.
For static builds dependency for SELinux libs is not handled by 'ar'.
Till better solution is found, for static builds STATIC_LIBS is used.

Patch updates SELinux detection to use 3rd & 4th parameter for Success/Fail.
Also removes detection of pthread from this check as we know which
version of libdevmapper we are going to link with lvm after merge.

SELinux header check moved to the SELinux test code.

f9d1b67e86 Readline linking update
Modify linking of readline library. Create new  substituted varible
READLINE_LIBS - readline library is linked ONLY with tools that really use
it - i.e. lvm. (Static lvm does not use readlin).
Previous behaviour put this library into the variable LIBS and thus
linked it with all created object files of lvm project (i.e. plugins...).

READLINE detection is simplified.

Termcap library is linked in only if readline library doesn't have its own
dependency (i.e. old distributions).

8cb8f65010 Handle a misaligned device that reports a -1 alignment_offset.
The kernel's blk_stack_limits() function may flag a device as
'misaligned'.  If it does the alignment_offset will be -1.

69962eae7c - fix whitespaces all over (tabs/spaces)
- increase timeout to 30 secs (on Chrissie request)
- source both cluster and clvmd for options (like all the other cluster
  init scripts)
- add clustered_vgs and _lvs commodity fns
- move rh_status* fns at the top, so they can be reused
- heavily cleanup start and stop fns from redundant code and unnecessary
  loops
- improve output from different operations
- make the init script lsb compliant
- don´t force kill of the daemon, send only a TERM signal and then wait
for it to exit
- Resolves rhbz#533247

40090be220 Always query device by uuid only.
lvm2 devices have always UUID set even if imported from lvm1 metadata.

Patch removes name argument from dev_manager_info call and converts
all activation related calls to use query by UUID.

Also it simplifies mknode call (which is the only user on mknodes parameter).

Fix add/remove tag function headers.
Fix a lot of little problems with doxygen comments.
Clarify the basic objects and their handles, and place functions with their
appropriate handles/objects.
All this cleanup moves automatic documentation of lvm2app much closer to being
useful as official documentation.  In the future I will add some examples
and plan to build the examples as part of the unit tests.

Add lvm2app functions to manage LV tags.
For lvm_lv_get_tags(), we return a list of tags, similar to other
functions that return lists.  An empty list is returned if there
are no tags.  NULL is returned if there is a problem obtaining
the list of tags.

befffd65bf Add tag_list_copy() supporting function inside lvm2app.
Add a supporting function to copy a list of internal tags to lvm2app list.
We need to put this here because of the lvm_str_list_t type which we export
in lvm2app.h.  If we didn't export this type, we could put this in the
internal library and use struct str_list.

610cd1a531 Add dm_pool_strdup to allocate memory and copy a tag in {lv|vg}_change_tag()
We need to allocate memory for the tag and copy the tag value before we
add it to the list of tags.  We could put this inside lvm2app since the
tools keep their memory around until vg_write/vg_commit is called, but
we put it inside the internal library to minimize code in lvm2app.
We need to copy the tag passed in by the caller to ensure the lifetime of
the memory until the {vg|lv} handle is released.
