Allow __ssp_inline to be overriden

PR/57689: RVP: getcwd() not overridable with -D_FORTIFY_SOURCE

PR/57288: Mingye Wang: <ssp/ssp.h>: Use __builtin_dynamic_object_size
for LLVM > 9 and GCC > 12, introducing _SSP_FORTIFY_LEVEL == 3

correct __ssp_overlap() to not trigger for adjacent areas

Allow SSP enabled functions to conditionally skip the object size check.
Use this is fix the getcwd(NULL, lmit) case, which breaks in lang/parrot.

add a macro to check overlapping pointers

sync with head

SSP mostly works with Clang, even if optimisation is disabled.
Explicitly disable it for Lint though.

Sync with HEAD

Redo the SSP wrappers to be transparent on the resulting object files.
This works by having the inline wrapper calling a second function which
uses renaming to output the correct function name.

Sync with HEAD

provide a way to override the weak name.

proved an __ssp_check macro.

Use the _sys alias instead of the _ alias as the way to access the baseline
syscall.

Re-do ssp hijacking by defining inline functions and using the weak libc
symbols to do the indirection for unistd.h instead of #define tricks.
Fixes compilation for things that define struct { ssize_t read(int fd, ...); }.

Use __dead instead of __attribute__((__noreturn__)) directly.

sync with head.

- Misc cleanups to make the code more readable.
- Detect if we are compiling in libc and provide the appropriate name.

Move FORTIFY_SOURCE implementation from the somewhat ill-named "libssp"
(what other systems keep in libssp, we already have in libc) into libc
to match what other systems with FORTIFY_SOURCE do.  Goodbye, libssp
dependency in libraries and executables.  Discussed with christos and
mrg; Christos will merge the headers to get us the rest of the way to a
FORTIFY_SOURCE implementation that works as others' code expects.
