Markus Armbruster 7828867198 error: Use error_report_err() instead of ad hoc prints
Unlike ad hoc prints, error_report_err() uses the error whole instead
of just its message obtained with error_get_pretty().  This avoids
suppressing its hint (see commit 50b7b00).  Example:

    $ bld/ivshmem-server -l 42@
    Parameter 'shm_size' expects a size
    You may use k, M, G or T suffixes for kilobytes, megabytes, gigabytes and terabytes.

The last line is new with this patch.

While there, drop a "cannot parse shm size: " message prefix; it's
redundant, because the error message proper is always of the form
"Parameter 'shm_size' expects ...".

Marc-André Lureau 1e21feb628 ivshmem-server: fix hugetlbfs support
As pointed out on the ML by Andrew Jones, glibc no longer permits
creating POSIX shm on hugetlbfs directly. When given a hugetlbfs path,
create a shareable file there.

interrupts using a ivshmem-server (typical use described in documentation).
The client is provided as a debug tool.
