The core library in theory has 0 dependencies, but in practice it has some in order for it to be efficient. These dependencies are in the form of the basic memory operations provided by libc traditionally, such as memset, memcmp, etc. These functions are trivial to implement and themselves have 0 dependencies. This commit adds a new crate, librlibc, which will serve the purpose of providing these dependencies. The crate is never linked to by default, but is available to be linked to by downstream consumers. Normally these functions are provided by the system libc, but in other freestanding contexts a libc may not be available. In these cases, librlibc will suffice for enabling execution with libcore. cc rust-lang#10116
