ipmi: replace IPMI_ADD_RSP_DATA() macro with inline helpers

Browse Source

The IPMI command handlers in the BMC simulator use a macro
IPMI_ADD_RSP_DATA() to push bytes in a response buffer. The macro
hides the fact that it implicitly uses variables local to the handler,
which is misleading.

This patch introduces a simple 'struct RspBuffer' and inlined helper
routines to store byte(s) in a response buffer. rsp_buffer_push()
replaces the macro IPMI_ADD_RSP_DATA() and rsp_buffer_pushmore() is
new helper to push multiple bytes. The latest is used in the command
handlers get_msg() and get_sdr() which are manipulating the buffer
directly.
