This reverts commit e1173011.

Reason for revert: The reverted test case is one of typical wrong wire
format test cases. The exposed API intentionally doesn't provide any
extenion object validation because the API is also used to construct
wire format compliance test tools. The API is extesion object-agnostic
and should be able to transmit and receive payload containing extension
objects in wrong wire format. Please preserve such test cases for now.

If you want to drop such test case, please add 1) extension object
validation, 2) a control knob for skipping validation, then drop all of
them.

Go's policy is to only support the past two releases (which is
currently Go 1.11 and Go 1.10). But because App Engine was stuck on Go
1.6 and Go 1.8 for so long, we kept kinda supporting Go 1.6 anyway,
even though we didn't actively test it with any CI system.

But that led to code getting disgusting and full of too many
+build-tagged files and indirection, as this change shows.

So, remove Go 1.8, Go 1.7, and Go 1.6 support. We still "support" Go
1.9 for now, even though it's also not actively tested.

Add a JumpIfX instruction which implements conditional jumps using
RegA and RegX. This is in addition to the pre-existing JumpIf
instruction which uses RegA and K.

This instruction / addressing mode is not mentionned in the original BPF
paper, but is supported by tools like bpf_asm, and has recently been
added to the kernel's filter.txt.

Simplify some of the parsing logic, and add a separate helper for
checking for "fake" JumpIfs.

Add JumpIfX support to the BPF vm.

Update testdata with JumpIfX instructions, and add tests
for both the assembler/disassembler and vm.

This generated 120 kB on the heap before at init, regardless of
whether somebody used http2. Worse, because we vendored it into std,
users would have two copies, for about 256 kB of memory. After CL
127235 that went down to 60 kB per copy, so 120 kB for a binary using
golang.org/x/net/http2 explicitly.

With this, it goes to 0 until one of the two copies in the binary
actually uses one of the http2 packages.

I wasn't able to measure any difference with the Once.Do in the decode
