Alexandre Julliard 4144b5b8fc Create the server directory and socket file in /tmp. 
Use fcntl file locking to ensure exclusion on the server socket and to
better recover from crashes.
Flush the registry before closing the socket to avoid timeouts on the
client side.
Moved get_config_dir functionality to libwine.

/*
reghack - windows 3.11 registry data format demo program.
The reg.dat file has 3 parts, a header, a table of 8-byte entries that is
a combined hash table and tree description, and finally a text table.
The header is obvious from the struct header. The taboff1 and taboff2
fields are always 0x20, and their usage is unknown.
The 8-byte entry table has various entry types.
tabent[0] is a root index. The second word has the index of the root of
the directory.
tabent[1..hashsize] is a hash table. The first word in the hash entry is
the index of the key/value that has that hash. Data with the same
hash value are on a circular list. The other three words in the
hash entry are always zero.
tabent[hashsize..tabcnt] is the tree structure. There are two kinds of
entry: dirent and keyent/valent. They are identified by context.
tabent[freeidx] is the first free entry. The first word in a free entry
is the index of the next free entry. The last has 0 as a link.
The other three words in the free list are probably irrelevant.
Entries in text table are preceded by a word at offset-2. This word
has the value (2*index)+1, where index is the referring keyent/valent
entry in the table. I have no suggestion for the 2* and the +1.
Following the word, there are N bytes of data, as per the keyent/valent
entry length. The offset of the keyent/valent entry is from the start
of the text table to the first data byte.
This information is not available from Microsoft. The data format is
deduced from the reg.dat file by me. Mistakes may
have been made. I claim no rights and give no guarantees for this program.

*
* the 1st entry in a "usual" registry file is a nul-entry with subkeys: the

* be any value.
*
* The "hash"-value is a value representing the key's name. Windows will not
* search for the name, but for a matching hash-value. if it finds one, it
* will compare the actual string info, otherwise continue with the next key.
* To calculate the hash initialize a D-Word with 0 and add all ASCII-values
* of the string which are smaller than 0x80 (128) to this D-Word.
*
* If you want to modify key names, also modify the hash-values, since they
* cannot be found again (although they would be displayed in REGEDIT)
* End of list-pointers are filled with 0xFFFFFFFF
*
* Disk keys are layed out flat ... But, sometimes, nrLS and nrMS are both
* 0xFFFF, which means skipping over nextkeyoffset bytes (including this
* structure) and reading another RGDB_section.
*
* The last DKE (see field last_dke in _w95_rgkn) has only 3 DWORDs with
* 0x80000000 (EOL indicator ?) as x1, the hash value and 0xFFFFFFFF as x3.
* The remaining space between last_dke and the offset calculated from
* rgkn->size seems to be free for use for more dke:s.
* So it seems if more dke:s are added, they are added to that space and
* last_dke is grown, and in case that "free" space is out, the space
* gets grown and rgkn->size gets adjusted.
*
* there is a one to one relationship between dke and dkh
