\r
Routine Description:\r
\r
  This function reads a line, stripping any comments.\r
  The function reads a string from the input stream argument and stores it in \r
  the input string. ReadLine reads characters from the current file position \r
  to and including the first newline character, to the end of the stream, or \r
  until the number of characters read is equal to MaxLength - 1, whichever \r
  comes first.  The newline character, if read, is replaced with a \0. \r
\r
Arguments:\r
\r
  InputFile     Memory file image.\r
  InputBuffer   Buffer to read into, must be MaxLength size.\r
  MaxLength     The maximum size of the input buffer.\r
\r
Returns:\r

  NULL if error or EOF\r
  InputBuffer otherwise\r

Arguments:\r
\r

  Section   The section to search for, a string within [].\r
  Token     The token to search for, e.g. EFI_PEIM_RECOVERY, followed by an = in the INF file.\r
