When a global pointer is not declared as constant, gcc will put it in
memory. Getting the address of the string it points to requires loading
the address of the pointer and then loading the pointer. When the pointer
is declared constant, the address of the string is loaded directly.

Now all threads need to ack the connection like on real target, dircache is unloaded and playback stops accordingly.

Also add two dircache function, one of which does what dircache_disable()
did previously as this now also frees the dircache buffer.

This enables the ability to allocate (and free) memory dynamically
without fragmentation, through compaction. This means allocations can move
and fragmentation be reduced. Most changes are preparing Rockbox for this,
which many times means adding a move callback which can temporarily disable
movement when the corresponding code is in a critical section.
For now, the audio buffer allocation has a central role, because it's the one
having allocated most. This buffer is able to shrink itself, for which it
needs to stop playback for a very short moment. For this,
audio_buffer_available() returns the size of the audio buffer which can
possibly be used by other allocations because the audio buffer can shrink.
lastfm scrobbling and timestretch can now be toggled at runtime without
requiring a reboot.

The buflib memory allocator is handle based and can free and
compact, move or resize memory on demand. This allows to effeciently
allocate memory dynamically without an MMU, by avoiding fragmentation
through memory compaction.
This patch adds the buflib library to the core, along with
convinience wrappers to omit the context parameter. Compaction is
not yet enabled, but will be in a later patch. Therefore, this acts as a
replacement for buffer_alloc/buffer_get_buffer() with the benifit of a debug
menu.
See buflib.h for some API documentation.

Namely, introduce buffer_get_buffer() and buffer_release_buffer().
buffer_get_buffer() aquires all available and grabs a lock, attempting to
call buffer_alloc() or buffer_get_buffer() while this lock is locked will cause
a panicf() (doesn't actually happen, but is for debugging purpose).
buffer_release_buffer() unlocks that lock and can additionally increment the
audiobuf buffer to make an allocation. Pass 0 to only unlock if buffer was
used temporarily only.
buffer_available() is a replacement function to query audiobuflen, i.e. what's
left in the buffer.
Buffer init is moved up in the init chain and handles ipodvideo64mb internally.
Further changes happened to mp3data.c and talk.c as to not call the above API
functions, but get the buffer from callers. The caller is the audio system
which has the buffer lock while mp3data.c and talk mess with the buffer.
mpeg.c now implements some buffer related functions of playback.h, especially
audio_get_buffer(), allowing to reduce #ifdef hell a tiny bit.
audiobuf and audiobufend are local to buffer.c now.

case, retrieve() and get_next() need to abort and take the ramcache
offline as well.

Check free space before reading new data from disk, and do not forget
to account for the RAM-cache header.

Only integer IDs are exposed from dircache with this. This way the cache is isolated from other modules.
This is needed for my buflib gsoc project.

returns ignored on import.

memory. One of these headers (current_tcmh) was not loaded in when
tagcache state was initialized from a hibernated state file (flashed
H1xx targets). That caused internal serial number to start always from
zero, rendering "recently played tracks" query not working as expected.

* There's no need to reset the buffer argument to
check_against_clauses to 0 when it's not needed. We can always
initialize str = buf and only change it on a RAM search hit.
* Do not memset buffer to 0 -- it's sufficient to make sure the
retrieved tag string is zero-terminated.
* Factor out a call to check_virtual_tags from two branches of an if
statement.

Optimization for the nonnumeric case: Only numerics are ever updated,
so there's no need to scan the command queue for updates to nonnumeric
tags.

Logical-AND ("&") always takes precedence over logical-OR.

Fight binsize increase by storing some common expressions in local

At least on android it blindly writes to the end of the buffer passed to it assuming it's sufficiently. It wasn't in our case, resulting in a buffer overflow (and breakage).
This should fix strange problems relating to database initialization on application targets.

Fix for FS#11856: In tagtree_buffer_event, do not wait for database to
come online as that may never happen. Rather, wait until it either
has come online or has decided that this will never happen. Added a
new function to tagcache.c to export this information.

First, it add the ability to tagcache to walk through multiple search roots.
Second, it adds symlinks targets to the search roots if they're are not inside any of the current search roots, otherwise the symlink is ignored (unless it's a file).
The default search root is still /, so no search root will be actually added.
But the tagcache now isn't trapped by recursive symlinks anymore and successfully builds, and it's prepared for a future music directory setting.

Use host's functions for file i/o directly (open(), close() ,etc.), not the sim_* variants.
Some dir functions need to be wrapped still because we need to cache the parents dir's path (host's dirent doesn't let us know).
For the same reason (incompatibility) with host's dirent) detach some members from Rockbox' dirent struct and put it into an extra one,
the values can be retrieved via the new dir_get_info().
Get rid of the sim_ prefix for sleep as well and change the signature to unix sleep().
