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

-Ein Ausdruck gilt als "wahr" sofern das Ergebnis weder NULL, nicht leer und von "0" abweichend ist.
+An expression is considered as "true" if it is not NULL, not empty, and different from "0".
-Für einen Vergleich werden Fließkommazahlen genutzt, insofern es sich bei beiden Ausdrücken um gültige Zahlen handelt, folgende Formate werden unterstützt:
+The comparison is made using floating point numbers if the two expressions are valid numbers, with one of the following formats:
-  - Integer (Beispiele: 5, -7)
+  - integer (examples: 5, -7)
-  - Fließkommazahl (Beispiele: 5.2, -7.5, 2.83e-2)

-  - hexadezimale Zahl (Beispiele: 0xA3, -0xA3)
+  - hexadecimal number (examples: 0xA3, -0xA3)
-Um einen Vergleich zwischen zwei Zeichenketten zu erzwingen, müssen die Ausdrücke in Anführungszeichen gesetzt werden, zum Beispiel:
+To force a string comparison, you can add double quotes around each expression, for example:
   50 > 100      ==> 0
   "50" > "100"  ==> 1

-Wyrażenie jest uznawane za „prawdziwe” jeśli nie jest NULL, nie jest puste, oraz różni się od „0”.
+An expression is considered as "true" if it is not NULL, not empty, and different from "0".
-Porównania dokonuje się z użyciem liczb całkowitych jeśli oba wyrażenia są liczbami całkowitymi, w jednym z następujących formatów:
+The comparison is made using floating point numbers if the two expressions are valid numbers, with one of the following formats:
-  - liczby całkowite (przykłady: 5, -7)
+  - integer (examples: 5, -7)
-  - liczby zmiennoprzecinkowe (przykłady: 5.2, -7.5, 2.83e-2)

-  - liczby szesnastkowe (przykłady: 0xA3, -0xA3)
+  - hexadecimal number (examples: 0xA3, -0xA3)
-W celu wymuszenia porównywania ciągów, należy umieścić każde wyrażenie w cudzysłowie, na przykład:
+To force a string comparison, you can add double quotes around each expression, for example:
   50 > 100      ==> 0
   "50" > "100"  ==> 1
 
-Niektóre zmienne w wyrażeniach są zamieniane, poprzez zastosowanie formatu ${zmienna}, według priorytetu zmienną może być:
