[v2,0/9] Misc fixes to pvrdma device

Hi,
Please review the following patch-set which consist of cosmetics fixes to
device's user interface (traces, error_report and monitor) and some bug
fixes.

Thanks Markus, Eric, Marcel and David for reviewing v0.
Appreciate your review to this v2.

Still missing r-b for patches 2, 4 and 6.

v0 -> v1:
    * Explain why device attributes are exposed only in HMP interface.
    * Squash the 3 patches related to HMP interface into one.
    * Make monitor dump function simple.
    * Make HMP interface available only if pvrdma is included (detected by
      build robot).
    * Remove patch 03/10 ("Warn when too many consecutive poll CQ triggered
      on an empty CQ) and add the two counters to patch 0/7 (monitor).
    * Add Marcel's R-Bs.
    * Add mutex protection to cqe_ctx list.
    * Add two new patches.

v1 -> v2:
    * Rename locked-lists to protected-lists in patch 2 and patch 6.
    * Add Marcel's R-Bs.

Thanks,
Yuval

clang compilation fails.
Please use this configuration:

     configure --target-list="x86_64-softmmu" --cc=clang --enable-pvrdma

It will fail with:
