Changes:
* Functions to compare arrays (compare, <, >, <=, >=) have been added
to the library array.s7i.
* In seed7_05.s7i the functions hashCode and compare have been
defined for enum types.
* In the library bigrat.s7i the operator parse has been improved. Now
the parse operator accepts decimal numbers with repeating decimals.
* The function integer has been added to the library integer.s7i.
This function converts a numeric string, with a specified radix, to
an integer.
* The function bigInteger has been added to the library bigint.s7i.
This function converts a numeric string, with a specified radix, to
a bigInteger.
* The files encoding.s7i, gethttp.s7i, scanfile.s7i, scanstri.s7i,
xml_ent.s7i and bas7.sd7 have been changed to use the new function
integer instead of toInt (toInt was an undocumented internal
function).
* Checks for the function integer have been added to chkint.sd7.
* Checks for the function bigInteger have been added to chkbig.sd7.
* The operator sci has been added to to the library complex.s7i. This
operater converts a complex to a string in scientific notation.
* The compiler (s7c) has been improved to support the actions
BIG_PARSE_BASED, TYP_CMP, ENU_CPY, ENU_CREATE and GEN_DESTR.
* The memory management in the interpreter has been improved. Now it
is possible that a destructor is called and the object memory is
not freed. This is used to free the memory of struct objects only,
when the usage_count reaches zero.
* The UNUSED flag was defined in data.h and used to monitor if the
object memory can be freed.
* The compiler has been improved to call the destructor for local
interface objects (In process_local_declaration process_destr_call
is called for INTERFACEOBJECT objects).
* The compiler has been improved to initialize set constants, that
are part of a data structure (In walk_const_list SETOBJECT objects
are added to set_const_table).
* The runtime library has been improved to use the action GEN_DESTR
instead of PRC_NOOP as destructor for integer and other simple
data types.
While here do some build with clang fixes
