FreeBSD's unlink ignores the file's own permission bits, so remove()
succeeds on a file the guest made read-only with chmod(0400). On Windows
the guest chmod sets FILE_ATTRIBUTE_READONLY, and DeleteFileW then fails
with ERROR_ACCESS_DENIED, which remove() reported as EACCES. Clear the
attribute and retry, restoring it if the retry still fails.

The repo allows one implementation per export. Move libc's rename into
libc/src/Rename.cpp, compile that file into both libc and libkernel, and
drop the second copy from libkernel's Stdio.cpp. FilesystemError moves to a
header so the shared source can use it.
The test now checks that the symbol it resolves belongs to libkernel (module
handle on Windows, dladdr on Linux) so it fails when the export is removed.

Opening a volume needs administrator rights, so the volume flush skipped
every volume in a normal user session. The libc, libkernel, save data and
app content file functions now record each host file and directory they
change. On Windows sceKernelSync flushes the recorded paths that changed
since the previous call, plus their changed parent directories, through
handles a normal user can open. Linux still calls sync().
Four sources defined NOMINMAX unconditionally, which redefines the macro the build already passes and warns on every MinGW build. Use the #ifndef guard the rest of the tree uses.
