A previous commit changed the allocation method for the call context to
include the method name string memory directly, so we must not treat the
method member separately anymore.

The invoked method name was separately duplicated from the call_context
structure. The structure itself is eventually freed by rpc_exec_reply()
but the method string it points to is lost after that.
Use calloc_a() instead to allocate the string copy buffer together with
the context structure, to ensure that all involved memory is freed.

This is required for plugins that need access to the configured execution
timeout. The global variable cannot be used as-is since we dlopen() with
RTLD_LOCAL.

RTLD_GLOBAL was used to allow plugins use each other symbols but this
facility was (most likely) never used and is a bad design anyway. If
there is a common code it should just go to a library.
Using RTLD_LOCAL on the other hand saves us from conflicting symbols
used by different plugins. An example can be iwinfo plugin using libnl.
If there appears to be another plugin using incompatible netlink
implementation this will result in a problem. Both plugins will start
using the same libnl which will break one of them.
