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.

Add test for ioctl(SIOCGIFCONF) and polyfill on BSDs - Use nullness checks when calling weakly linked functions. - Avoid typedef for reasons described in Linux Kernel style guide. - Avoid enum in in Windows headers. Earlier in Cosmo's history all one hundred files in libc/nt/enum/ used to be enums and it resulted in gigabytes of DWARF data almost as large as everything else in the codebase combined. - Bitfields aren't our friends. They have frequent ABI breakages, inconsistent arithmetic across compilers, and different endianness between cpus. Compiler authors also haven't invested much roi into making bit fields go fast so they produce poor assembly. - Use memccpy() instead of strncpy() or snprintf() for length-bounded copying of C strings. strncpy() is a misunderstood function and snprintf() is awesome but memccpy() deserves more love.
