qapi: Fix C identifiers generated for names containing '.'

c_fun() maps '.' to '_', c_var() doesn't. Nothing prevents '.' in
QAPI names that get passed to c_var().

Which QAPI names get passed to c_fun(), to c_var(), or to both is not
obvious. Names of command parameters and struct type members get
passed to c_var().

c_var() strips a leading '*', but this cannot happen. c_fun()
doesn't.

Fix c_var() to work exactly like c_fun().

Perhaps they should be replaced by a single mapping function.
