[PATCH v3 00/10] Cleanup xdfile_t and xrecord_t in xdiff.

["Ezekiel Newren via GitGitGadget" <gitgitgadget@gmail.com>]

Changes since v2.

 * No patch changes, just resending to get patch 9 to show up on the mailing
   list.
 * A few tweaks to the cover letter.

Changes since v1, to address review feedback.

 * Only include the clean up patches; The remaining patches will be split
   into a separate series.
 * Commit message clarifications.
 * Minor style cleanups.
 * Performance impacts included in commit message of patch 8.


Relevant part of the original cover letter follows:
===================================================

Before:

typedef struct s_xrecord {
	struct s_xrecord *next;
	char const *ptr;
	long size;
	unsigned long ha;
} xrecord_t;

typedef struct s_xdfile {
	chastore_t rcha;
	long nrec;
	unsigned int hbits;
	xrecord_t **rhash;
	long dstart, dend;
	xrecord_t **recs;
	char *rchg;
	long *rindex;
	long nreff;
	unsigned long *ha;
} xdfile_t;


After cleanup:

typedef struct s_xrecord {
	char const *ptr;
	long size;
	unsigned long ha;
} xrecord_t;

typedef struct s_xdfile {
	xrecord_t *recs;
	long nrec;
	long dstart, dend;
	char *rchg;
	long *rindex;
	long nreff;
} xdfile_t;
