2469e07784 UE: only write libc and libsystem location once 
This is important when emulating UE itself, which maps these files
two times, and then we forget the original location of it.

9e2e36724d LibCpp: Add TemplatizedName 
This type represents templatized names, and replaces our previous use
of 'TemplatizedType' and 'TemplatizedFunctionCall'.

Also, we now parse function calls as secondary expressions.

7648f6aa7b HackStudio: File search box stays opened after closing

cbd62c472e UserspaceEmulator: Default-initialize the siginfo struct used in waitid 
Otherwise it'll have some random value from the stack, and the kernel
will not bother setting it to zero.
Also add a debug print and tweak the FIXME message.

77601e09c8 FontEditor+TextEditor+Playground: Refuse to load device files 
This prevents the undefined behaviour that would come up as a result of
doing so. (For example: opening "infinite" devices like /dev/full will
result in an infinite loop until exhaustion of memory)

e0f32626bc LibGfx: Rename 32-bit BitmapFormats to BGRA8888 and BGRx888x 
The previous names (RGBA32 and RGB32) were misleading since that's not
the actual byte order in memory. The new names reflect exactly how the
color values get laid out in bitmap data.

292871c4bc UserspaceEmulator: Handle MAP_FIXED with invalid addresses better 
Old behavior: Crash due to VERIFY, unless we're completely and entirely out of
memory (m_available_ranges being empty), in which case it would return -ENOMEM.

New behavior: Return ENOMEM (and don't crash). In the case of nullptr,
also emit a helpful diagnostic.

Note that MAP_FIXED with nullptr is technically okay, but tends to be a sign
that something went wrong.

Also, this should improve mmap performance marginally, as it pulls the check out
of a loop that does not modify any parts of the check.

UE is now self-hosting! Fixes #5709.

However, this still needs some love: "ue UserspaceEmulator true" spits out tons
of error messages, probably false-positives, and takes about 229 seconds to run.
Then again, true-in-ue-in-ue-in-Qemu is three levels of emulation, so no wonder
it takes a long time! :D

22d9bd0c45 UserspaceEmulator: Do not pass MAP_FIXED to Kernel 
Since there is usually no correlation between guest memory-layout and UE memory-layout,
this option does not make any sense. Especially since we provide nullptr.

c192b6c61d Emulator: Use libc.so bounds to fast-reject non-malloc addresses 
The auditing code always starts by checking if we're in one of the
ignored code ranges (malloc, free, realloc, syscall, etc.)

To reduce the number of checks needed, we can cache the bounds of
the LibC text segment. This allows us to fast-reject addresses that
cannot possibly be a LibC function.
