Continuation of #489 with a few changes:
_AT_SYSINFO_EHDR
tag to the end of the auxv test before_AT_NULL
to test unmatched/fallthrough cases (ehdr used to be the first element in the vector)ReadAll()
since we don't have any control over its size. Avoids most allocs at the cost of more reads but auxv is already an in-memory structure in practice. Also being a bit more liberal regarding alignment, removing the double-buffering and reading it using an anon struct with Tag and Val fields.unix.ByteSliceToString
for reading nul-terminated stringsThanks @brycekahle!
