Because fcntl locks don't nest, we track them in the tdb->lockrecs array and only place/release them when the count goes to 1/0. We only do this for record locks, so we simply place the list number (or -1 for the free list) in the structure. To generalize this: 1) Put the offset rather than list number in struct tdb_lock_type. 2) Rename _tdb_lock() to tdb_nest_lock, make it non-static and move the allrecord check out to the callers (except the mark case which doesn't care). 3) Rename _tdb_unlock() to tdb_nest_unlock(), make it non-static and move the allrecord out to the callers (except mark again).

compression - Various compression algorithms (MSZIP, lzxpress)
nss_wrapper - Wrapper for the user and group NSS API allowing the use
of other data sources.
popt - Command-line option parsing library
replace - Provides replacements for standard (POSIX, C99) functions
not provided by the host platform.
socket_wrapper - Wrapper library allowing TCP/IP traffic to be redirected
over Unix domain sockets.
talloc - Hierarchical pool based memory allocator
tdb - Simple but fast key/value database library, supporting multiple writers
