5062cb111b changed XXH_PRIVATE_API to XXH_INCLUDE_BODY 
now includes `xxhash.h` instead of `xxhash.c`, which feels more natural

80c3562c60 Reorder operation to avoid warning for unary minus operator for unsigned type 
For example, VC++ shows the following warnings:

1>  xxhsum.c
1>..\..\xxhsum.c(620): warning C4146: unary minus operator applied to unsigned type, result still unsigned
1>..\..\xxhsum.c(621): warning C4146: unary minus operator applied to unsigned type, result still unsigned

The folliwing thread is good pointer for unary minus operators behaviour:

C: unary minus operator behavior with unsigned operands
http://stackoverflow.com/questions/8026694/

> 6.2.5c9 says: A computation involving unsigned operands can never overflow,
> because a result that cannot be represented by the resulting unsigned
> integer type is reduced modulo the number that is one greater than the
> largest value that can be represented by the resulting type.

2783350952 Add redundant case for gcc -Wswitch-enum 
- gcc -Wswitch-enum warns them.  But this is completely false-positive.

xxhsum.c:956:13: warning: enumeration value ‘GetLine_ok’ not handled in switch [-Wswitch-enum]
             switch (getLineResult)

c93b51c22e Implement variable length line reader. 
- Basic logic is same as GNU coreutil's lib/getline.c and lib/getdelim.c
 - Since this implementation fully depends on fgetc(), there is possible performance problem.

5c8aab6e6a Fix line number related definitions 
- To keep code simple, now line number is "unsigned long" instead of "size_t".
 - We use "%ul" to print unsigned long.

f47e8e1ff8 Add file check mode "-c" and related switches. 
- Add the following command line switches
    - "-c"/"--check" : read XXH32/64 sums from FILEs and check them.
    - "--quiet" : Don't print OK.
    - "--status" : Don't output anything to stdout/stderr.
    - "--strict" : Treat any invalid line as error.
    - "--warn" : Show warning message for invalid line.
 - If all checksum procedure is succeeded, exit code is 0.
    - Otherwise exit code is 1.

All avobe functions basic logics are inherited from md5sum.

1090f766c2 Split hash generation function for reusing 
- Add hash generation function BMK_hashStream() which generates hash value from file stream.
 - First argument void* is not violate strict aliasing, but dedicated union may be good for readability.
