+ A class for handling Valgrind output.
+
+ Valgrind errors look like this:
+
+ ==60741== 40 (24 direct, 16 indirect) bytes in 1 blocks are definitely lost in loss record 2,746 of 5,235
+ ==60741== at 0x4C26B43: calloc (vg_replace_malloc.c:593)
+ ==60741== by 0x63AEF65: PR_Calloc (prmem.c:443)

+ ==60741== by 0xA042443: ffi_call (ffi64.c:485)
+
+ For each such error, this class extracts most or all of the first (error
+ kind) line, plus the function name in each of the first few stack entries.
+ With this data it constructs and prints a TEST-UNEXPECTED-FAIL message that
+ TBPL will highlight.
+
+ It buffers these lines from which text is extracted so that the
+ TEST-UNEXPECTED-FAIL message can be printed before the full error.
+
+ Parsing the Valgrind output isn't ideal, and it may break in the future if
+ Valgrind changes the format of the messages, or introduces new error kinds.
+ To protect against this, we also count how many lines containing
+ "<insert_a_suppression_name_here>" are seen. Thanks to the use of
+ --gen-suppressions=yes, exactly one of these lines is present per error. If
+ the count of these lines doesn't match the error count found during
+ parsing, then the parsing has missed one or more errors and we can fail
+ appropriately.
