The change eliminates the fixed size buffers in gen_suppression and
show_used_suppressions. This is achieved by changing the return type from
VG_TDICT_CALL(tool_get_extra_suppression_info and
VG_TDICT_CALL(tool_print_extra_suppression_use from Bool to SizeT.
A return value of 0 indicates that nothing (except the terminating '\0'
which is always inserted) was written to the buffer. This corresponds to the
previous False return value. A return value which is equal to the buffer
size (that was passed in as function argument) indicates that the buffer was
not large enough. The caller then resizes the buffer and retries.
Otherwise, the buffer was large enough.
Regtested with a resize value of 1.

Option -v outputs a list of used suppressions. This only gives
the nr of times a suppression was used.
For a leak search, this only gives the nr of loss records that
have been suppressed, but it does not give additional needed details
to understand more precisely what has been suppressed
(i.e. nr of blocks and nr of bytes).
=> Add in the tool interface update_extra_suppression_use and
print_extra_suppression_info functions to allow the tool to record
additioonal use statistics for a suppression. These statistics
can be done depending on the error (and its data) which is suppressed.
Use this in memcheck for the leak suppressions, to maintain and output
the nr of blocks and bytes suppressed by a suppression during
the last leak search.

If a suppression file contains an error, the lineno reported could be wrong.
Also, give filename and lineno of the used suppressions in -v debugging output.
The fix consists in ensuring that tool specific read_extra function gets
the Int* lineno pointer, together with other VG_(get_line) parameters.
