+/******************* DATABASE MODULE ***************************/
+
+/* Notes (as I think of them):
+- The module is 100% thread-safe
+- The database is the main routing point for the vast majority of Miranda.
+ Events are sent from the protocol module to here, and the send/recv message
+ module (for example) hooks the db/event/added event. Events like 'contact
+ online status changed' do not come through here - icqlib will send that one.
+- contacts work much the same. the find/add users module calls db/contact/add
+ and db/contact/writesetting and the contact list will get db/contact/added
+ and db/contact/settingchanged events
+- The user is just a special contact. A hcontact of NULL in most functions
+ means the user. Functions in which it cannot be used will be stated
+- events attached to the user are things like system messages
+- also in this module are crypt/decrypt functions for stuff that should be
+ obfuscated on the disk, and some time functions for dealing with timestamps
+ in events.
+- the contactsettings system is designed for being read by many different
+ modules. eg lots of people will be interested in "ICQ"/"UIN", but the module
+ name passed to contact/writesetting should always be your own. The Mirabilis
+ ICQ database importer clearly has to be an exception to this rule, along with
+ a few other bits.
+- the current database format means that geteventcontact is exceptionally slow.
+ It should be avoidable in most cases so I'm not too concerned, but if people
+ really need to use it a lot, I'll sort it out.
+- handles do not need to be closed unless stated
+- the database is loaded as a memory mapped file. This has various
+ disadvantages but a massive advantage in speed for random access.
+- The database is optimised for reading. Write performance is fairly bad,
+ except for adding events which is the most common activity and pretty good.
+- I'll work on caching to improve this later
+- Deleted items are left as empty space and never reused. All new items are
+ put at the end. A count is kept of this slack space and at some point a
+ separate programme will need to be written to repack the database when the
+ slack gets too high. It's going to be a good few months of usage before this
+ can happen to anyone though, so no rush.

+This service differs from db/contact/getsetting in that it won't malloc()

+is a string or a blob the service needs to know where to put the data and will
+fail if type is set wrongly.
+If dbcgs.pValue->type is DBVT_ASCIIZ or DBVT_BLOB upon calling, the
+corresponding data field (pszVal or pbVal) must point to a buffer allocated by
+the caller and the length field (cchVal or cpbVal) must contain the size of
+that buffer in bytes.
+If the setting type is variable length (DBVT_ASCIIZ or DBVT_BLOB), on exit the
+length field (cchVal or cpbVal) will be filled with the full length of the
+setting's value (excluding the terminating nul if it's DBVT_ASCIIZ).
