Remove xmalloc, xcalloc, xrealloc and xstrdup from utils.h and revert calls
to the normal malloc, calloc, realloc, strdup. Add new files malloc_wrap.[ch]
with the wrapper functions. malloc_wrap.h #defines malloc etc. to the
wrapper, but only if USE_MALLOC_WRAPPERS has been defined.
Put #include "malloc_wrap.h" in any file that uses *alloc or strdup. This
is also in a #ifdef USE_MALLOC_WRAPPERS ... #endif block to make using the
wrappers optional. Add -DUSE_MALLOC_WRAPPERS into the makefile so they
should normally get added.
This is an improvement on the previous method as we now don't need to
worry about stray function calls that were not changed to the wrapped version
and the code will still work even if the wrapping is disabled.
Other possible methods of doing this are using malloc_hook (glibc-specific),
adding -include malloc_wrap.h to the gcc command-line (somewhat
gcc-specific) or making our own malloc function and using dlopen (scary).
This way is probably the most portable.
Added a new utils.c wrapper err_gzclose and changed gzclose calls to use it.
Put in some more err_fflush calls before files being written are closed.
Made err_fflush call fsync. This is useful for remote filesystems where
errors may not be reported on fflush or fclose as problems at the server
end may only be detected after they have returned. If bwa is being used
only to write to local filesystems, calling fsync is not really necessary.
To disable it, comment out #define FSYNC_ON_FLUSH in utils.c.
In Casava 1.8 the fastq output changed. e.g.
@EAS139:136:FC706VJ:2:5:1000:12850 1:Y:18:ATCACG
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
+
BBBBCCCC?<A?BC?7@@???????DBBA@@@@A@@
The part after the space, treated as comment by bwa, contains the fields:
<read number>:<is filtered>:<control number>:<barcode sequence>
With `Y' Casava indicates that a sequence should be filtered. This patch
enables bwa, with an -Y flag, to filter these sequences.

wasn't parsing correctly. This patch fixes that and enables bwa to filter
sequences marked by Casava, removing this tag from the output.
