api: add support of pointer names in function string_eval_expression (direct and in hdata)

These two formats are now supported, if "pointer_name" is present in the
"pointers" hashtable:

* "${pointer_name}": value of pointer (example: "0x1234abcd")
* ${buffer[pointer_name].full_name}: use of a pointer name instead of pointer
  value or list name

   20. a hdata name/variable (the value is automatically converted to string), by default "window" and "buffer" point to current window/buffer.
 Format for hdata can be one of following:
   hdata.var1.var2...: start with a hdata (pointer must be known), and ask variables one after one (other hdata can be followed)
-  hdata[list].var1.var2...: start with a hdata using a list, for example:
+  hdata[list].var1.var2...: start with a hdata using a list/pointer/pointer name, for example:
     ${buffer[gui_buffers].full_name}: full name of first buffer in linked list of buffers
     ${plugin[weechat_plugins].name}: name of first plugin in linked list of plugins
   hdata[pointer].var1.var2...: start with a hdata using a pointer, for example:
     ${buffer[0x1234abcd].full_name}: full name of the buffer with this pointer (can be used in triggers)
+    ${buffer[my_pointer].full_name}: full name of the buffer with this pointer name (can be used in triggers)
 For name of hdata and variables, please look at "Plugin API reference", function "weechat_hdata_get".
