v0 protocol: use size_t for capability length/offset
When parsing server capabilities, we use "int" to store lengths and offsets. At first glance this seems like a spot where our parser may be confused by integer overflow if somebody sent us a malicious response. In practice these strings are all bounded by the 64k limit of a pkt-line, so using "int" is OK. However, it makes the code simpler to audit if they just use size_t everywhere. Note that because we take these parameters as pointers, this also forces many callers to update their declared types.
