57dc179b1f Everywhere: Rename to_{string => deprecated_string}() where applicable
This will make it easier to support both string types at the same time
while we convert code, and tracking down remaining uses.

One big exception is Value::to_string() in LibJS, where the name is
dictated by the ToString AO.

6e19ab2bbc AK+Everywhere: Rename String to DeprecatedString
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)

ae3ffdd521 AK: Make it possible to not using AK classes into the global namespace
This patch adds the `USING_AK_GLOBALLY` macro which is enabled by
default, but can be overridden by build flags.

This is a step towards integrating Jakt and AK types.

c70f45ff44 Everywhere: Explicitly specify the size in StringView constructors
This commit moves the length calculations out to be directly on the
StringView users. This is an important step towards the goal of removing
StringView(char const*), as it moves the responsibility of calculating
the size of the string to the user of the StringView (which will prevent
naive uses causing OOB access).

This was not used anywhere in the kernel anyway.

210b0b883b AK: Remove unused ifdef for BUILDING_SERENITY_TOOLCHAIN
The only use of this define was removed in commit
5f724b6ca1, over a year ago.

The define was there to prevent the LibC build we built before libstdc++
from complaining about missing libgcc symbols. However, as noted in that
commit, we never actually needed to build LibC at all.

1682f0b760 Everything: Move to SPDX license identifiers in all files.
SPDX License Identifiers are a more compact / standardized
way of representing file license information.

See: https://spdx.dev/resources/use/#identifiers

This was done with the `ambr` search and replace tool.

4361a50225 AK: Don't demangle in serenity :(
In order to remove libstdc++ completely, we need to give up on their
implementation of abi::__cxa_demangle. The demangler logic will actually
have to be quite complex, and included in both the kernel and userspace.

A definite fixme for the future, to parse the mangled names into real
deal names.

9dbab2d05e Misc: Replace "String(string_view)" with "string_view.to_string()"
StringView::to_string() was added in 917ccb1 but not actually used
anywhere yet.

7d862dd5fc AK: Reduce header dependency graph of String.h
String.h no longer pulls in StringView.h. We do this by moving a bunch
of String functions out-of-line.

c600280dde AK: The <cxxabi.h> header is not available during Toolchain build
This will need some refinement, but basically since we build LibC
during the toolchain build, we don't have libstdc++ headers yet.

94ca55cefd Meta: Add license header to source files
As suggested by Joshua, this commit adds the 2-clause BSD license as a
comment block to the top of every source file.

For the first pass, I've just added myself for simplicity. I encourage
everyone to add themselves as copyright holders of any file they've
added or modified in some significant way. If I've added myself in
error somewhere, feel free to replace it with the appropriate copyright
holder instead.

Going forward, all new source files should include a license header.

c6e552ac8f Kernel+LibELF: Don't blindly trust ELF symbol offsets in symbolication
It was possible to craft a custom ELF executable that when symbolicated
would cause the kernel to read from user-controlled addresses anywhere
in memory. You could then fetch this memory via /proc/PID/stack

We fix this by making ELFImage hand out StringView rather than raw
const char* for symbol names. In case a symbol offset is outside the
ELF image, you get a null StringView. :^)

c24fe710d7 AK: Turn off demangler in userland
For some reason, the default CXXFLAGS and such don't get us the
__cxa_demangle symbol in userland.

f75a6b9daa Kernel: Demangle kernel C++ symbols correctly again
I broke this while implementing module linking. Also move the actual
demangling work to AK, in AK::demangle(const char*)
