[PATCH v1 00/14] various fixes for next PR (testing, vhost, guest_base fixes)

[Alex Bennée]

Hi,

These are all the patches I've currently got which are ready for a
pull request next week. I've included some patches which are destined
to go in via other trees so I can keep the testing green on the CI.

In summary:

 Some simple plugin cleanups (the reset remain in plugins/next)
 Reliability fixes for travis/shippable
 iotest 194 fix (going in via block tree?)
 docker updates (ubuntu and tricore fix)
 vhost-user and TCG fix
 more linux-user guest_base fixes

I'll certainly include the testing stuff in my PR but if others are
happy for me to include bits touching their areas then shout and I'll
include them in the PR.

The following need review:

 - linux-user: detect overflow of MAP_FIXED mmap
 - linux-user: deal with address wrap for ARM_COMMPAGE on 32 bit
 - linux-user: provide fallback pgd_find_hole for bare chroots
 - tests/docker: fix pre-requisite for debian-tricore-cross
 - hw/virtio/vhost: re-factor vhost-section and allow DIRTY_MEMORY_CODE
 - .shippable: temporaily disable some cross builds
 - exec: flush the whole TLB if a watchpoint crosses a page boundary
