this is mostly useless for shared libs (though it could help for prelink-like purposes); the intended use case is for adding support for calling the dynamic linker directly to run a program, as in: ./libc.so ./a.out foo this usage is not yet supported.

prior to this change, copy relocations for initialized pointer variables would not reflect the relocated contents of the pointer.

deps can be null if a library has no dependencies (such as libc itself)

basically we temporarily make the library and all its dependencies part of the global namespace but only for the duration of performing relocations, then return them to their former state.

some of the code is not yet used, and is in preparation for dlopen which needs to be able to handle failure loading libraries without terminating the program.

1. search was wrongly beginning with lib itself rather than dso head 2. inconsistent resolution of function pointers for functions in plt

first, use $LD_LIBRARY_PATH unless suid. if that fails, read path from /etc/ld-musl-$ARCH.path and fallback to a builtin default.

eventually (once dlopen exists) this behavior will be conditional on dlopen/dlsym not being reachable.

the use of this test will be much stricter than glibc and other typical implementations; the environment will not be honored whatsoever unless the program is confirmed non-suid/sgid by the aux vector the kernel passed in. no fallback to slow syscall-based checking is used if the kernel fails to provide the information; we simply assume the worst (suid) in this case and refuse to honor environment.

some notes: - library search path is hard coded - x86_64 code is untested and may not work - dlopen/dlsym is not yet implemented - relocations in read-only memory won't work
