BUGFIX: Issue #15 -- iconv input/output buffer should be dynamically allocated for M:N conversion.
* N:1 conversion may exhaust input buffer, EINVAL case and not input buffer
  consumpution need to increase the buffer.
* 1:N conversion with irreversible chars(such as GNU libiconv //TRANSLIT)
  may exhaust output buffer, so E2BIG case need to increase the buffer.
