RedfishPkg/RedfishCrtLib: Redfish C runtime library

Redfish CRT library is currently used by edk2 JsonLib
(open source jansson project) and edk2 RedfishLib
(libredfish open source project). Redfish CrtLib library
provides the necessary C runtime equivalent edk2 functions
for open source projects.

+/** The strtol, strtoll, strtoul, and strtoull functions convert the initial

+    portion of the string pointed to by nptr to long int, long long int,

+    unsigned long int, and unsigned long long int representation, respectively.

+    First, they decompose the input string into three parts: an initial,

+    possibly empty, sequence of white-space characters (as specified by the

+    isspace function), a subject sequence resembling an integer represented in

+    some radix determined by the value of base, and a final string of one or

+    more unrecognized characters, including the terminating null character of

+    the input string. Then, they attempt to convert the subject sequence to an

+    integer, and return the result.

+

+    If the value of base is zero, the expected form of the subject sequence is

+    that of an integer constant, optionally preceded

+    by a plus or minus sign, but not including an integer suffix. If the value

+    of base is between 2 and 36 (inclusive), the expected form of the subject

+    sequence is a sequence of letters and digits representing an integer with

+    the radix specified by base, optionally preceded by a plus or minus sign,

+    but not including an integer suffix. The letters from a (or A) through z

+    (or Z) are ascribed the values 10 through 35; only letters and digits whose

+    ascribed values are less than that of base are permitted. If the value of

+    base is 16, the characters 0x or 0X may optionally precede the sequence of

+    letters and digits, following the sign if present.

+

+    The subject sequence is defined as the longest initial subsequence of the

+    input string, starting with the first non-white-space character, that is of

+    the expected form. The subject sequence contains no characters if the input

+    string is empty or consists entirely of white space, or if the first

+    non-white-space character is other than a sign or a permissible letter or digit.

+

+    If the subject sequence has the expected form and the value of base is

+    zero, the sequence of characters starting with the first digit is

+    interpreted as an integer constant. If the subject sequence has the

+    expected form and the value of base is between 2 and 36, it is used as the

+    base for conversion, ascribing to each letter its value as given above. If

+    the subject sequence begins with a minus sign, the value resulting from the

+    conversion is negated (in the return type). A pointer to the final string

+    is stored in the object pointed to by endptr, provided that endptr is

+    not a null pointer.

+

+    In other than the "C" locale, additional locale-specific subject sequence

+    forms may be accepted.

+

+    If the subject sequence is empty or does not have the expected form, no

+    conversion is performed; the value of nptr is stored in the object pointed

+    to by endptr, provided that endptr is not a null pointer.

+

+  @return   The strtol, strtoll, strtoul, and strtoull functions return the

+            converted value, if any. If no conversion could be performed, zero

+            is returned. If the correct value is outside the range of

+            representable values, LONG_MIN, LONG_MAX, LLONG_MIN, LLONG_MAX,

+            ULONG_MAX, or ULLONG_MAX is returned (according to the return type

+            and sign of the value, if any), and the value of the macro ERANGE

+            is stored in errno.
