8a81716325 Minor fixes 
Just small updates and remove <backtrace> after log_error.

c452307543 Few more close and dev_close trace 
Adding (void) where we cannot really report an error.

c5b8faf3b1 Explicitely ignore fail error on hash_insert 
We cannot do anything better here anyway - we are already in logging function,
so just ignore this issue here - it will most likely stop application later.

84fd8ea4bd Move done jump lower 
Since before 'goto done' is bufused zeroed, it would otherwise write 1
byte in front of buffer.

5dfd775384 Ensure strncpy() function always ends with '\0' 
Since last character needs to be \0 for string,
pass buffer size smaller by 1 byte.

9e453cab1c Reduce stack size usage in print_log 
As the buf2[] and locn[] can't be used at the same time, safe 1 page from
stack memory.

df336e72d2 Optimise error message write to _lvm_errmsg 
Isn't usually perfomance critical - but log_error is used i.e.for debuging,
this code noticable slows down the processing.

Added 512KB limit to avoid memory exhastions in case of some endless loop.

TODO: use _lvm_errmsg buffer only when lvm2api needs it.

b1bcff7424 Critical section 
New strategy for memory locking to decrease the number of call to
to un/lock memory when processing critical lvm functions.

Introducing functions for critical section.

Inside the critical section - memory is always locked.
When leaving the critical section, the memory stays locked
until memlock_unlock() is called - this happens with
sync_local_dev_names() and sync_dev_names() function call.

memlock_reset() is needed to reset locking numbers after fork
(polldaemon).

The patch itself is mostly rename:

memlock_inc  -> critical_section_inc
memlock_dec  -> critical_section_dec
memlock      -> critical_section

Daemons (clmvd, dmevent) are using memlock_daemon_inc&dec
(mlockall()) thus they will never release or relock memory they've
already locked memory.

Macros sync_local_dev_names() and sync_dev_names() are functions.
It's better for debugging - and also we do not need to add memlock.h
to locking.h header (for memlock_unlock() prototyp).

99a304bc17 Optionally abort on internal errors (and leverage this option in the 
testsuite). (This is showing a problem in the pvmove test for me, so I expect
the tests to start failing -- this needs to be fixed separately though.)
