Over past months a performance issue was found with the Mesa-DB cache
implementation that results in a too slow cache startup time when cache is
full. A better indexing strategy will need to be invented to mitigate the
issue. Until then, let's default back to the multi-file cache.

In !25925 I attempted to fix an error spam caused by the disk cache not
creating parent directories of the cache directory when needed,
resulting in failure to create the disk cache. Presumably that is bad
for performance.
Unfortunately I did a really bad job and only fixed the edge case where
the cache dir is given by $MESA_SHADER_CACHE_DIR rather than the general
case. Here I attempt to be more comprehensive.

The `capture_not_overwritten` unit test captures and compares two
backtraces -- one from inside a call to `func_c` and one outside -- and
confirms that they are not identical. That is, that `func_c` is in the
backtrace.
On 32-bit x86, without `-fno-omit-frame-pointer`, the function will not
emit a stack frame. As a result, the unit test fails.
The fix is to compile `func_c` with the flag `-fno-omit-frame-pointer`
to prevent the compiler from optimizing out the stack frame which is
otherwise unneeded.

An "augmented tree" is a tree with extra data attached which flows from
the leaves to the root. An "interval tree" is a datastructure of
(potentially-overlapping) intervals where, in addition to inserting and
removing intervals, we can quickly lookup all the intervals which
overlap a given interval.
After describing red-black trees, CLRS explains how it's possible to
implement an interval tree using an augmented red-black tree where the
nodes are ordered by interval start and each node also stores the
maximum interval end for its entire subtree.
Implement the interval tree extension described by CLRS. Iterating over
all overlapping intervals is actually an exercise, so we have to solve
the exercise. The recursive solution has been re-written to use the
parent pointers to avoid needing a stack, similarly to rb_tree_first()
and rb_node_next().
For now, we only implement unsigned intervals, but the core algorithms
are all abstracted to allow other types. There's still some boilerplate,
but it's the best that can be done in C.

In the linear allocator, when a size larger than the minimum
buffer size is allocated, we currently create the new buffer
to fit exactly the requested size.
In that case, don't bother updating the `latest` pointer, since
this newly created buffer is already full. In the worst case,
the current `latest` is full and it would be the same; in the
best case, there's still room for small allocations, so we avoid
wasting space if the next allocations would fit.

Whenever a single file mesa-db cache hits max size limit, a half of cache
is evicted and the cache file is defragmented. The downside of this eviction
strategy is that it causes high disk IO usage during eviction if mesa-db
cache file size is large.
In order to mitigate this downside, we will split mesa-db into multiple
part such that only one part will be evicted at a time. Each part will be
an individual single file mesa-db cache, like a DB shard. The new multipart
mesa-db cache will merge the parts into a single virtual cache.
This patch introduces two new environment variables:
1. MESA_DISK_CACHE_DATABASE_NUM_PARTS:
Controls number of mesa-db cache file parts. By default 50 parts will be
created. The old pre-multipart mesa-db cache files will be auto-removed
if they exist, i.e. Mesa will switch to the new DB version automatically.
2. MESA_DISK_CACHE_DATABASE_EVICTION_SCORE_2X_PERIOD:
Controls the eviction score doubling time period. The evicted DB part
selection is based on cache entries size weighted by 'last_access_time' of
the entries. By default the cache eviction score is doubled for each month
of cache entry age, i.e. for two equally sized entries where one entry is
older by one month than the other, the older entry will have x2 eviction
score than the other entry. Database part with a highest total eviction
score is selected for eviction.
This patch brings x40 performance improvement of cache eviction time using
multipart cache vs a single file cache due to a smaller eviction portions
and more optimized eviction algorithm.

Add a new environment varible
MESA_DISK_CACHE_READ_ONLY_FOZ_DBS_DYNAMICE_LIST that specifies a text
file containing a list of RO fossilize caches to load. The list file
is modifiable at runtime to allow for loading RO caches after
initialization unlike MESA_DISK_CACHE_READ_ONLY_FOZ_DBS.
The implementation spawns an updater thread that uses inotify to monitor
the list file for modifications, attempting to load new foz dbs added to
the list. Removing files from the list will not evict a loaded cache.
MESA_DISK_CACHE_READ_ONLY_FOZ_DBS_DYNAMIC_LIST takes an absolute path.
The file must exist at initialization for updating to occur.
File names of foz dbs in the list file are new-line separated and take
relative paths to the default cache directory like
MESA_DISK_CACHE_READ_ONLY_FOZ_DBS.
The maximum number of RO foz dbs is kept to 8 and is shared between
MESA_DISK_CACHE_READ_ONLY_FOZ_DBS_DYNAMIC_LIST and
MESA_DISK_CACHE_READ_ONLY_FOZ_DBS.
The intended use case for this feature is to allow prebuilt caches
to be downloaded and loaded asynchronously during app runtime.

conditions would otherwise present extended wait time for caches
to be availible before app launch.

Mesa utilizes only one type of cache at a time. This patch enables support
for combined reading from read-only Fossilize cache + non-foz read-write
caches.
From now on, a non-foz read-write caches will first try to retrieve data
from a read-only foz cache if new MESA_DISK_CACHE_COMBINE_RW_WITH_RO_FOZ
environment variable is set to true, otherwise the caching behaviour is
unchanged. The new flag has no effect when MESA_DISK_CACHE_SINGLE_FILE=1,
i.e. when the single-file foz cache is used.
This change allows us to ship a prebuilt RO caches for a certain
applications, while the rest of applications will benefit from the
regular RW caching that supports cache-size limitation. This feature
