A sweep of the sparse code prompted by a bug report by Jim Meyering.

to use umaxtostr.
(xheader_format_name): Don't assume pids and uintmax_t values
fit in 63 bytes (!) when printed.

(sparse_size_decoder, sparse_offset_decoder, sparse_numblocks_decoder):
Ensure that the result of calling xstrtoumax is no larger than
the maximum value for the target type. Upon any failure, exit with
a diagnostic.
(sparse_numblocks_decoder): Avoid buffer overrun/heap corruption:
use x2nrealloc, rather than `n *= 2' and xrealloc(p, n,....
(decode_time): Rewrite to accept time strings like
1119018481.
000000000. Before, such strings were always ignored.
