07113beea3 Do not scan device if it is part of active multipath.
Add filter which tries to check if scanned device is part
of active multipath.

Firstly, only SCSI major number devices are handled in filter.

Then it checks if device has exactly one holder (in sysfs) and
if it is device-mapper device and DM-UUID is prefixed by "MPATH-".

If so, this device is filtered out.

The whole filter can be switched off by setting
mpath_component_detection in lvm.conf.

cac52ca4ce Add basic RAID segment type(s) support.
Implementation described in doc/lvm2-raid.txt.

Basic support includes:
- ability to create RAID 1/4/5/6 arrays
- ability to delete RAID arrays
- ability to display RAID arrays
Notable missing features (not included in this patch):
- ability to clean-up/repair failures
- ability to convert RAID segment types
- ability to monitor RAID segment types

b171907fc5 Refactor metadata.[ch] into lv.[ch] for lv functions.
This patch is similar to the other patches for pv and vg
functionality, and separates lv functionality into separate
files, concentrating on reporting fields and simple functions.

f42b708eae Refactor metadata.[ch] into pv.[ch] for pv functions.
The metadata.[ch] files are very large.  This patch makes a first
attempt at separating out pv functions and data, particularly
related to the reporting fields calculations.

More code could be moved here but for now I'm stopping at reporting
functions 'get' / 'set' functions.

fc65b9038e Add properties.[ch] to lib/report, defined based on columns.h.
Extend the existing reporting infrastructure definitions and structures
to include a 'get' and 'set' function for each field.  We will provide
a 'get' and 'set' function for each of these fields, which will be utilized
by exported lvm2app functions.

Define a default _not_implemented 'get' and 'set' function that just sets
an errno and returns 0.  Future patches will actually implement the
specific 'get' and 'set' functions for each property.  For read-only
properties, only the 'get' function will be implemented.

Define vg_get_property() function to query a property.  We will call
this from a lvm2app function.

727f7bfa49 Detect LUKS signature in pvcreate
One shiny day we should use libblkid here. But now using LUKS is
very common together with LVM and pvcreate destroys LUKS completely.

So for user's convenience, try to detect LUKS signature and allow abort.

23b059e7b7 INSTALL rules updates
Patch is inspired by Debian's extra patch.

- removes OWNER & GROUP make vars they are parts of INSTALL command.
- adds INSTALL_PROGRAM for executable, uses $(INSTALL)
- adds INSTALL_DATA for non-executable data, uses ($INSTALL)
- adds INSTALL_WDATA for writable non-executable data, uses ($INSTALL)
- adds configure option --enable-write_install - to support
  installatin of writable files used by distribution
- replaces usage of ifeq @LIB_SUFFIX@ with $(LIB_SUFFIX)
- installs .a files from static builds without executable flag
- installs .a files to $(usrlibdir) instead of $(libdir)
- installs all static binaries to $(staticdir)
- create .so links for devel package in $(usrlibdir) instead of
  $(libdir)
- makes .so and .so.LIB_VERSION files within builddir
- removes VERSIONED_SHLIB and created versioned LIB_SHARED automagicaly
- install LIB_SHARED via install_lib_shared target
- install plugins via install_lib_shared_plugin target
- prints whole 'install' command during installation instead of less
  informative "Installing  $(something) $(somewhere)"
- install multiple man pages with one INSTALL command
- use DISTCLEAN_TARGETS instead of creating multiple distclean targets

c737d34804 Use vpath instead of VPATH.
Usage of VPATH makes troubles when used within $(builddir).
Not only source files are being found through VPATH,
but targets as well. (make --debug=v)

Thus if user builds the code in $(srcdir) and also in some $(builddir)
he gets mangled results as some generated files (i.e. .export.sym)
are 'reused' from $(srcdir) instead of $(builddir).

This patch switches to use vpath were we could explicitly name
suffixes that should be looked via vpath - we must take care,
we do not generate files with these suffixes:
.c, .in, .po, .exported_symbols

b41f5924bf Update cflow file generation - support build dir and use $(top_srcdir)
to obtain sources. Create make.tmpl target for
simplier generation of cflow files with the help of
CFLOW_LIST, CFLOW_LIST_TARGET, CFLOW_TARGET.
Still cflow usage is not perfect.

1a91d0914e distclean fixes
Move daemons/ and lib/ subtargets to their Makefiles so we don't get
double cleanup error during execution of distclean target.

just use it as a subtarget and avoid add duplicating code.

b6deac338f Build shared parts with 'make' command (mpatocka)
When some parts of lvm are built as shared libraries (for example with
--with-snapshots=shared), the 'make' command does not build these parts.
The shared parts are built with 'make install' command.

This bug can be seen if you go to 'lib' subdirectory and type 'make'.
If you type 'make', the shared libraries are not built, if you type
'make all', the shared libraries are built.

The reason for the bug is the line $(SUBDIRS): $(LIB_STATIC)
If make is executed without any arguments, it makes the first target
in the Makefile. If the first target is '$(SUBDIRS): $(LIB_STATIC)',
it only builds static libraries.

This patch moves '$(SUBDIRS): $(LIB_STATIC)' after
include $(top_srcdir)/make.tmpl. make.tmpl contains the 'all' target
as its first target, so 'make' will be equivalent to 'make all' and
shared libraries will be build with 'make' command.

e0c64c6c35 Add new liblvm build directory and move lvm_base.c.
The original liblvm.a has been moved to liblvm-internal.a.
We now use liblvm.a for the new application library and build
it inside liblvm directory.

Change dependencies so tools depend on liblvm application library,
and application library depends on liblvm internal.

New structure lvm (used as an alias to cmd_context), new type definition lvm_t
for the lvm handle. Added functions lvm_create, lvm_destroy and
lvm_reload_config using the new handle.

Modified test/api/test.c:
Use new lvm.h header file and lvm_t handle.

Removed lib/lvm2.h
