[PATCH 2/3] use alloc_ref_from_str() everywhere

Replace pairs of alloc_ref() and strcpy() with alloc_ref_from_str(), simplifying the code.

In connect.c, also a pair of alloc_ref() and memcpy() is replaced -- the additional cost of a strlen() call should not have too much of an impact. Consistency and simplicity are more important.

In remote.c, the code was allocating 11 bytes more than needed for the name part, but I couldn't see them being used for anything.
