FD_SET is limited to 1024 file descriptors in Linux, which causes
processes with too many open files or connections to crash:
FORTIFY: FD_ISSET: file descriptor 1024 >= FD_SETSIZE 128
The fix we used elsewhere is replacing select() with poll(), but in the
case of SocketListener we additionally need to replace the SocketClient
list with a map indexed by fd in order to avoid quadratic behavior on
each poll() wakeup.
Bug: 79838856
Test: device boots and appears to work normally, tests pass

Moved headers from include/libutils and include/libsysutils to
libutils/include and libsysutils/include respectively, so they can be
exported via these libs. They needed to be moved since Soong does
not allow export from external folder.
Added symlink from old locations. They are needed since Soong
includes system/core/include by default. Once all modules are
cleaned up to explicitly add the required libs, the symlinks will be
removed.
Moved headers of libutils to libutils_headers. They should be used
by modules for header-only inlines. Added libutils_headers as
dependency of libutils.
Split of C++ headers into those that have no dependency and those that
have dependency on libutils.so will be handled in a later CL.
Test: Add above libs to shared lib of local module
