* Feature:
* 1: If a property name declared befor any section is declared, it
* is in a "global" section. If the ini_read_* function argument
* section is empty string or NULL, they will find the property
* name in the "global" section.
* 2: There is no technical LIMIT on the length of section name or
* property name or value, or the num of sections and properties,
* the limit is the size of memory.
* 3: There is no special limit on the name of section and property.
* Note that the surround whitespace of the name of section and
* property and value is ignored, but they can contian whitespace.
* Note that the name of section and property are case insensitivity.
* 4: Blank line is ignored.
* 5: Lines beginning with '#' or ';' are ignored and may be used to
* provide comments.
* 6: The second occurrence of a property name in the same section
* overwrite the previous one. The section occurrence of a section
* is joined whih the previous one.
* 7: If a line end with '\', where a backslash followed immediately
* by EOL (end-of-line) causes the line break to be ignored, and
* the "logical line" to be continued on the next actual line from
* the INI file. Example:
* name = simple read only ini parser
* is the same with:
* name = simple \
* read only \
* ini parser
* Load a ini config file to memory, return NULL if fail.
ini_t *ini_load(char *path);
* Return value:
* If the combination of section and name found in config file, return 0.
* Return 1 if not found, the *value will be the default_value.
* Fail return -1;
* Read string from ini config handler.
* The string is allocated using malloc, so, you need free it after use.
