Read data from one or more files. This routine is used by algorithms needing to
read all data into memory.
readFileData reads in all data from a set of files. Data is returned as an array
of InputBlock structs. Normally one InputBlock per file, sized to match the size
of the file. Standard input is read in one or more blocks, as are files whose size
cannot be determined. Multiple blocks are used in these last two cases to avoid
expensive memory reallocations. This is not necessary when file size is known as
the necessary memory can be preallocated.
Individual lines never span multiple blocks, and newlines are preserved. This
means that each block starts at the beginning of a line and ends with a newline
unless the end of a file has been reached. Each file gets its own block so that
header processing can be done.
