386886f71c config: refer to config nodes using assigned IDs
For example, the old call and reference:

  find_config_tree_str(cmd, "devices/dir", DEFAULT_DEV_DIR)

...now becomes:

  find_config_tree_str(cmd, devices_dir_CFG)

So we're referring to the named configuration ID instead
of passing the configuration path and the default value
is taken from central config definition in config_settings.h
automatically.

3acc85caa8 buffering: use unbuffered silent mode for liblvm

When private stdin/stdout buffering is not used always use silent
mode.

53dd32f41d Add proper udev library context initialization and finalization to liblvm.
This was missing in liblvm and it caused all udev-related operations to
not take effect when using liblvm, e.g. obtaining the list of devices from udev
db instead of scanning the whole /dev which also recreated the .cache as a side
effect. This was also the case with udisks-lvm-pv-export prober which is run
from within udev rules whenever the CHANGE event is fired.

eee66d2a80 When glibc needs buffers for line buffering of input and output buffers, it
allocates these buffers in such way it adds memory page for each such buffer
and size of unlock memory check will mismatch by 1 or 2 pages.

This happens when we print or read lines without '\n' so these buffers are
used. To avoid this extra allocation, use setvbuf to set these bufffers ahead.

66781f5d5a Fix wrong cast to char*
As cmd->cmd_line is already const char pointer it's not needed to cast already
const char pointer to char pointer.

0d23926e4e Add lvm2app interfaces to lookup a vgname from a pvid and pvname.
lvm2app forces applications to start with a volume group name,
open the volume group, then operate on individual pvs.  In some
cases the application may want to start with a device name rather
than the volume group name.  Today, if an application wants to
do this, it must iterate through all the volume groups to find
the volume group that the specific device is attached to.
These new interfaces allow the application to avoid such overhead.
Bump the lvm2app version number to 3.

917c57e77b Disable long living process flag in lvm2app.
This option should be configurable, but for now
do not set it at all.

(lvm2app is used in udisks probers and there
cac cause several nasty races when trying to update
lvmcache during rescan.)

98d85f25be Move error message to locking constructor and print
more descriptive message if locking fails instead of
"Locking type -1 initialisation failed."

Use read-only locking instead of misleading ignorelocking option
in message.

dce56c9761 Add lvm_config_override - allow caller to override config, similar to --config.
Allowing the caller to override the LVM configuration with an API will
enable them to use things such as device filters.
While very flexible, there is some danger to this API in that it will
make it harder to debug setups that have a changing config and deduce
what might have happened.  At some point we may want to limit the scope
of this API but for now it is as open as the --config option to lvm commands.

Update exported symbols.  When I renamed lvm_reload_config to lvm_config_reload
I forgot to rename so I renamed that one here.

This I believe is the last liblvm API for now.  ;-)

f6b1eaf700 Rename lvm_reload_config to lvm_config_reload.
The general naming scheme for most liblvm APIs is:
lvm_<object>_<action>

As there are likely to be other things to do on the lvm 'config' object
(i.e. lvm_config_set_device_filter), we should use consistent naming.

f864285b3a Update liblvm status return codes to be consistent.
For now, we use the following scheme.
For APIs that return an int, success is 0, fail is -1.
APIs that return handles, success is non-NULL, fail is NULL.
At this early stage, liblvm error handling mechanism is subject to change,
but for now we go with this simple scheme consistent with system
programming.

d917192f00 Add lvm_errno and lvm_errmsg to liblvm to obtain failure information.

9c5a7b0481 Add default cmd->cmd_line initialization for liblvm lvm_create().
This needs initialized to non-NULL before using the archive() call.
Normally this is set to the cmdline string when lvm is called from a tool.
We could think about using it in another way, as a potential audit trail
of liblvm calls, or just leave it set to the default "liblvm", similar to
what clvmd does.  For now, just set it to "liblvm".

470304e2a2 Remove unnecessary includes in lvm_base.c.
We would like to declare our handles pv_t, vg_t, and lv_t in
the external library header lvm.h.  However, these are already
defined in metadata-exported.h for the use of some of the
in-progress liblvm APIs.  Thus, we cannot both define
them in lvm.h and include metadata-exported.h in the external
library C files.  We could use preprocessor tricks (#ifndef)
but for now we just avoid the include.

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.
