4c389f6edf disas: Move host asm annotations to tb_gen_code 
Instead of creating GStrings and passing them into log_disas,
just print the annotations directly in tb_gen_code.

Fix the annotations for the slow paths of the TB, after the
part implementing the final guest instruction.

e5ef4ec28b disas: include an optional note for the start of disassembly 
This will become useful shortly for providing more information about
output assembly inline. While there fix up the indenting and code
formatting in disas().

cbafa2362a plugin: add qemu_plugin_insn_disas helper 
Give the plugins access to the QEMU dissasembler so they don't have to
re-invent the wheel. We generate a warning when there are spare bytes
in the decode buffer. This is usually due to the front end loading in
more bytes than decoded.

ec150c7e09 include: Make headers more self-contained 
Back in 2016, we discussed[1] rules for headers, and these were
generally liked:

1. Have a carefully curated header that's included everywhere first.  We
   got that already thanks to Peter: osdep.h.

2. Headers should normally include everything they need beyond osdep.h.
   If exceptions are needed for some reason, they must be documented in
   the header.  If all that's needed from a header is typedefs, put
   those into qemu/typedefs.h instead of including the header.

3. Cyclic inclusion is forbidden.

This patch gets include/ closer to obeying 2.

It's actually extracted from my "[RFC] Baby steps towards saner
headers" series[2], which demonstrates a possible path towards
checking 2 automatically.  It passes the RFC test there.

d49190c420 disas: Remove uses of CPU env 
disas does not need to access the CPU env for any reason. Change the
APIs to accept CPU pointers instead. Small change pattern needs to be
applied to all target translate.c. This brings us closer to making
disas.o a common-obj and less architecture specific in general.
