SymbolMap had no coverage. It stores symbols relative to a module so they
survive that module being unloaded and reloaded elsewhere, and only symbols
belonging to a loaded module count as active - that indirection is where the
surprises are, so the tests concentrate on module lifetime and the shared label
table.
Writing them turned up a real bug. UpdateActiveSymbols() bailed out early when
activeModuleEnds was empty, as a "tiny optimization" for startup and shutdown,
having already cleared the active maps. But symbols with module index 0 are
absolute by design - they belong to no module, which is how you label a heap or
stack address - and the loops it skipped are exactly what keeps those alive.
So an absolute symbol disappeared as soon as the last module was unloaded, and
didn't exist at all before the first one was loaded. Dropping activeModuleEnds
from the early-out condition fixes it; the symbol-count half still gives the
intended fast path when there's nothing to do.
Tests cover function and data lookup by containing address, SetFunctionSize,
RemoveFunction/RemoveData, symbols surviving an unload/reload at a different
address, absolute (module 0) symbols, GetSymbolInfo/GetDescription, and Clear.
Two of them pin down behaviour that catches people out rather than asserting
it's right: AddLabel deliberately won't overwrite an existing label, and because
functions and data share one label table, renaming or removing via one affects
the other.

Windows/MainWindowMenu.cpp's Load/Save/Clear Symbol Map menu actions
mutated g_symbolMap directly from the WinMain thread; route them through
Core_RunOnCPUThread like the rest of the debugger. Windows/MainWindow.cpp's
WM_USER_GET_MODULE_INFO handler read it directly too; guard with
g_frameMutex. Windows/main.cpp's SortSymbols() calls turn out to already be
safe as-is - both notifications that trigger them (BOOT_DONE,
SYMBOL_MAP_UPDATED) are only ever fired from the CPU/NativeFrame thread -
so just fix the stale comment claiming reliance on the (now removed)
internal lock.
With those covered, every remaining caller is either on the CPU/NativeFrame
thread already or routes through Core_RunOnCPUThread/g_frameMutex, so
SymbolMap's internal recursive_mutex is redundant - remove it and all ~40
lock_guard call sites. Qt's mainwindow.cpp still pokes at g_symbolMap
directly and unguarded (a pre-existing issue, out of scope - Qt isn't a
maintained backend), but removing the lock doesn't change its public API,
so it still builds.

Reverse-engineering workflows need to (1) find where an unknown value lives
in memory and (2) label what's found, neither of which the debugger API
could do before:
- memory.search (MemorySubscriber.cpp): Cheat-Engine-style scan of a memory
range for a u8/u16/u32/float value, or a byte pattern with an optional
wildcard mask.
- hle.data.list/add/remove/rename (HLESubscriber.cpp): manage ST_DATA
symbols (structs, tables, buffers), mirroring the existing hle.func.*
commands for functions. Needed a new SymbolMap::RemoveData, since only
RemoveFunction existed - added following the same pattern.
Verified live against a running PPSSPP instance (game.status, cpu.stepping,
memory.search in u32/bytes/masked-bytes modes, and the full
add/list/rename/remove data-symbol lifecycle) via Tools/wsdbg.

* Rename LogType to Log
* Explicitly use the Log:: enum when logging. Allows for autocomplete when editing.
* Mac/ARM64 buildfix
* Do the same with the hle result log macros
* Rename the log names to mixed case while at it.
* iOS buildfix
* Qt buildfix attempt, ARM32 buildfix
Tested games with lots of functions, it's just never worth generating the
full active symbols. Direct lookup saves 0.005s startup on desktop in a
typical game.
* Move and rename file_util/fd_util to Common/File/FileUtil and DirListing
Let's also move net while we're at it.
Move the ZIM/PNG loaders over to Common.
Move the UI framework into Common
iOS buildfix
* Buildfix
* Buildfixes
* Apple buildfix
* This typo again..
* UWP buildfix
* Fix build of PPSSPPQt, such as it is (it's not in good condition...)
* Guess what? Another buildfix.
Also move colorutil.cpp/h
linking build fix experiment
Delete a bunch of unused CMakeLists.txt files
CMakeLists.txt linking fix
Don't include NativeApp.h from any headers.
Android.mk buildfix
Half of the UWP fix
Buildfix
Minor project file cleanup
Buildfixes
Guess what? More buildfixes!
