receive inv's (omitted from testing description below, this is our control).
Second node is used for creating reorgs.
test_null_locators
==================
Sends two getheaders requests with null locator values. First request's hashstop
value refers to validated block, while second request's hashstop value refers to
a block which hasn't been validated. Verifies only the first request returns
headers.
test_nonnull_locators
=====================
Part 1: No headers announcements before "sendheaders"
a. node mines a block [expect: inv]
send getdata for the block [expect: block]
