568a417224 Enforce a standard header file guard symbol name
Require that all headers are guarded by a symbol named

  LIBVIRT_$FILENAME

where $FILENAME is the uppercased filename, with all characters
outside a-z changed into '_'.

Note we do not use a leading __ because that is technically a
namespace reserved for the toolchain.

4cfd709021 Fix many mistakes & inconsistencies in header file layout
This introduces a syntax-check script that validates header files use a
common layout:

  /*
   ...copyright header...
   */
  <one blank line>
  #ifndef SYMBOL
  # define SYMBOL
  ....content....
  #endif /* SYMBOL */

For any file ending priv.h, before the #ifndef, we will require a
guard to prevent bogus imports:

  #ifndef SYMBOL_ALLOW
  # error ....
  #endif /* SYMBOL_ALLOW */
  <one blank line>

The many mistakes this script identifies are then fixed.

5165ff0971 src: More cleanup of some system headers already contained in internal.h
All of the ones being removed are pulled in by internal.h. The only
exception is sanlock which expects the application to include <stdint.h>
before sanlock's headers, because sanlock prototypes use fixed width
int, but they don't include stdint.h themselves, so we have to leave
that one in place.

33470896e5 tests: qemumonitorutils: Don't crash on wrong monitor command
virQEMUQAPISchemaPathGet returns success when a given schema path was
not found but the returned object is set to NULL. This meant that we'd
call testQEMUSchemaValidate with the schemaroot being NULL which lead to
a crash if a mistyped monitor command was tested.

7ef0471bf7 qemu: don't retry connect() if doing FD passing
Since libvirt called bind() and listen() on the UNIX socket, it is
guaranteed that connect() will immediately succeed, if QEMU is running
normally. It will only fail if QEMU has closed the monitor socket by
mistake or if QEMU has exited, letting the kernel close it.

With this in mind we can remove the retry loop and timeout when
connecting to the QEMU monitor if we are doing FD passing. Libvirt can
go straight to sending the QMP greeting and will simply block waiting
for a reply until QEMU is ready.

85af0b803c qemu: Adaptive timeout for connecting to monitor
There were couple of reports on the list (e.g. [1]) that guests
with huge amounts of RAM are unable to start because libvirt
kills qemu in the initialization phase. The problem is that if
guest is configured to use hugepages kernel has to zero them all
out before handing over to qemu process. For instance, 402GiB
worth of 1GiB pages took around 105 seconds (~3.8GiB/s). Since we
do not want to make the timeout for connecting to monitor
configurable, we have to teach libvirt to count with this
fact. This commit implements "1s per each 1GiB of RAM" approach
as suggested here [2].

9046f910bd tests: monitor: json: Fix error message when returning json in json
The qemu JSON monitor test allows to test also expected command
arguments. As the error from the monitor simulator is returned as a
simulated qemu error (in JSON) all other JSON contained in the error
message needs to be escaped. This will happen if the monitor command
under test receives a JSON array as an argument.

This will improve the error message from:
libvirt:  error : internal error: cannot parse json { "error":  { "desc":
"Invalid value of argument 'keys' of command 'send-key': expected 'ble'
got '[{"type":"number","data":43},{"type":"number","data":26},
{"type":"number","data":46},{"type":"number","data":32}]'",
"class": "UnexpectedCommand" } }: lexical error: invalid string in json text.

To:
libvirt: QEMU Driver error : internal error: unable to execute QEMU
command 'send-key': Invalid value of argument 'keys' of command
'send-key': expected 'ble' got '[{"type":"number","data":43},
{"type":"number","data":26},{"type":"number","data":46},
{"type":"number","data":32}]'

This improvement will not have any effect on tests executing as
expected, but it will help test development.

though we can clearly see worker has run (nobody else sets @running =
