1c92911e9e [libc] apply new lint rules
This patch applies the lint rules described in the previous patch. There
was also a significant amount of effort put into manually fixing things,
since all of the templated functions, or structs defined in /spec, were
not updated and had to be handled manually.

c120edc7b3 [libc][nfc] move ctype_utils and FPUtils to __support
Some ctype functions are called from other libc functions (e.g. isspace
is used in atoi). By moving ctype_utils.h to __support it becomes easier
to include just the implementations of these functions. For these
reasons the implementation for isspace was moved into
ctype_utils as well.

FPUtils was moved to simplify the build order, and to clarify which
files are a part of the actual libc.

Many files were modified to accomodate these changes, mostly changing
the #include paths.

049cfc464d [libc] Rename FEnv.h and refactor subsequent files
Because Windows's pathnames are not case sensitive,
to avoid include conflicts between our header file FEnv.h and the
one from the C Standard library, <fenv.h>, the prior file was renamed.
The motive for the relabel came to fix this include error in
TestHelpers.cpp since a conflict arose with a file in the same
directory when #include <fenv.h> was being used.

a0b65a7bcd [libc] Switch to use a macro which does not insert a section for every libc function.
Summary:
The new macro also inserts the C alias for the C++ implementations
without needing an objcopy based post processing step. The CMake
rules have been updated to reflect this. More CMake cleanup can be
taken up in future rounds and appropriate TODOs have been added for them.
