Even though rpc uses 'unsigned int' for the _len parameter that
passes the length of item<length>, the public libvirt APIs all
use 'int' and filter out lengths < 0, except for virDomainSendKey.
* include/libvirt/libvirt.h.in (virDomainSendKey): All other APIs
use int for array length.
* src/libvirt.c (virDomainSendKey): Adjust.
* src/driver.h (virDrvDomainSendKey): Likewise.
* daemon/remote_generator.pl: Likewise.
The position of the struct parameter in the function signature
differs. Instead of hardcoding the handling for this add an annotation
to the .x file to define the position.
After successfull virDomainSave/virDomainManagedSave calls
the guest will no longer be active, so the domain ID must
be reset to -1
* daemon/remote_generator.pl: Special case virDomainSave &
virDomainManagedSave for same reason as virDomainDestroy
Remove some special case code that took care of mapping hyper to the
correct C types.
As the list of procedures that is allowed to map hyper to long is fixed
put it in the generator instead annotations in the .x files. This
results in simpler .x file parsing code.
Use macros for hyper to long assignments that perform overflow checks
when long is smaller than hyper. Map hyper to long long by default.

In most cases this affects flags parameters that are unsigned in the
public and driver API but signed in the XDR protocol. Switch the
XDR protocol to unsigned for those.
A counterexample is virNWFilterGetXMLDesc. Its flags parameter is signed
in the public API and XDR protocol, but unsigned in the driver API.
virNodeGetFreeMemory used unsigned long long in the public API but
signed hyper in the XDR protocol. Convert the XDR protocol to use
unsigned hyper.
As explained by Eric before, this doesn't affect the on-the-wire protocol.
Several functions return values by reference parameters. This is realized
by passing the members of remote_CALL_ret by reference to the called
function.
The position of this parameters in the function signature follows some
patterns with some exceptions. This patterns and exceptions are hardcoded
in the generator.
Add an insert@<offset> annotation to the remote_CALL_ret struct members
for functions that return lists to remove some of the hardcoded patterns
and exceptions.
The on-the-wire protocol is identical; XDR guarantees that
both 'hyper' and 'unsigned hyper' are transmitted as 8 bytes.
* src/remote/remote_protocol.x (remote_get_version_ret)
(remote_get_lib_version_ret): Match public API.
* daemon/remote_generator.pl: Drop special case.
* src/remote_protocol-structs: Reflect updated type.
The public API and RPC over-the-wire format have no flags argument,
so neither should the internal callback API. This simplifies the
RPC generator.
* src/driver.h (virDrvNWFilterDefineXML): Drop argument that does
not match public API.
* src/nwfilter/nwfilter_driver.c (nwfilterDefine): Likewise.
* src/libvirt.c (virNWFilterDefineXML): Likewise.
* daemon/remote_generator.pl: Drop special case.
This matches the public API and helps to get rid of some special
case code in the remote generator.
Rename driver API functions and XDR protocol structs.
No functional change included outside of the remote generator.
In preparation for removing generated files, it is necessary
to tell automake that the generated files must be distributed
but not directly compiled (since they are included into the
body of a larger .c file that is compiled). Hence, even though
these files are code and not headers in the strict sense of
the word, it is easier to rename them to .h for automake's sake.
* daemon/remote_client_bodies.c: Rename to .h.
* daemon/qemu_client_bodies.c: Likewise.
* src/remote/remote_client_bodies.c: Likewise.
* src/remote/qemu_client_bodies.c: Likewise.
* daemon/Makefile.am (remote_dispatch_bodies.c)
(qemu_dispatch_bodies.c): Rename to .h.
(remote.c, EXTRA_DIST): Reflect rename.
* daemon/remote.c: Likewise.
* daemon/remote_generator.pl: Likewise.
* src/Makefile.am (remote/remote_driver.c): Likewise.
* src/remote/remote_driver.c: Likewise.
* po/POTFILES.in: Likewise.
* cfg.mk (exclude_file_name_regexp--sc_require_config_h)
(exclude_file_name_regexp--sc_require_config_h_first)
(exclude_file_name_regexp--sc_prohibit_empty_lines_at_EOF):
Likewise.
This patch just covers the simple functions without explicit return
values. There is more to be handled.
The generator collects the members of the XDR argument structs and uses
this information to generate the function bodies.
Exclude the generated files from offending syntax-checks.
