Add `dontthrow` attribute to most libc functions This will help C++ code that uses exceptions to be tinier. For example, this change shaves away 1000 lines of assembly code from LLVM's libcxx, which is 0.7% of all assembly instructions in the entire library.

Replace COSMO define with _COSMO_SOURCE This change might cause ABI breakages for /opt/cosmos. It's needed to help us better conform to header declaration practices.

Create ELF aliases for identical symbols This change greatly reduces the number of modules that need to be compiled. The only issue right now is that sometimes when viewing symbol table entries, the aliased symbol is chosen.
