[kudu-CR] rpc: fix too-long memcmp for HTTP methods

Hello Dan Burkert,

I'd like you to do a code review.  Please visit

rpc: fix too-long memcmp for HTTP methods

Previously we were using arraysize(kHTTPHeader) where kHTTPHeader is a
constant "HTTP". This array would then include the terminating null
byte, which is length 5 rather than the expected length 4.

This switches to using strlen.

[kudu-CR] rpc: fix too-long memcmp for HTTP methods

Hello Kudu Jenkins,

I'd like you to reexamine a change.  Please visit

    http://gerrit.cloudera.org:8080/4992

to look at the new patch set (#2).

rpc: fix too-long memcmp for HTTP methods

Previously we were using arraysize(kHTTPHeader) where kHTTPHeader is a
constant "HTTP". This array would then include the terminating null
byte, which is length 5 rather than the expected length 4.
This switches to using strlen instead of arraysize.

This fixes the following ASAN error seen occasionally in tests:
