1d57562942 sendkey: use consistent API convention
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.

9fbfcd3b44 remote generator: Handle struct returning functions better (part 2)
Commit 64000eabed is part 1, that only covered the daemon side by
accident. Part 2 covers the client side too.

64000eabed remote generator: Handle struct returning functions better
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.

13488f55c5 Make sure virDomainSave/virDomainManagedSave reset id to -1
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

32abd5ee26 remote generator: Legacy support for hyper to long mappings
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.

Suggested by Eric Blake.

1ff2b6f6ee Fix sign mismatches between public API, driver API and XDR protocol
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.

30e9b1a186 remote generator: Fix XDR sign mismatch for virNodeGet(Cells)FreeMemory
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.

77582e7f3f remote generator: Make call-by-reference handling stricter
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.

8fcbc0c63c remote: remove special case for getting version
The on-the-wire protocol is identical; XDR guarantees that
both 'hyper' and 'unsigned hyper' are transmitted as 8 bytes.

d3c5104dda build: rename generated files to .h, for automake's sake
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.

aff1db9fab remote generator, daemon: Output function bodies too
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.
