Right, so I started playing with this, added a global Makefile to tools/
and from there we descend into lib/ and perf/ in that order to prepare
all the modules for the perflib. I've played with the include paths so
that you can have #include <util/util.h> for all that generic library
stuff.
The patch below carves out the debugfs helpers along with some generic
headers, please take a look and let me know if this is an agreeable
direction I'm going. Yeah, it is big, I think vger won't be able to
swallow it but this is only moving files around so...
Thanks.

+/*
+ * Strbuf's can be use in many ways: as a byte array, or to store arbitrary
+ * long, overflow safe strings.
+ *
+ * Strbufs has some invariants that are very important to keep in mind:
+ *
+ * 1. the ->buf member is always malloc-ed, hence strbuf's can be used to
+ * build complex strings/buffers whose final size isn't easily known.
+ *
+ * It is NOT legal to copy the ->buf pointer away.
+ * `strbuf_detach' is the operation that detachs a buffer from its shell
+ * while keeping the shell valid wrt its invariants.
+ *
+ * 2. the ->buf member is a byte array that has at least ->len + 1 bytes
+ * allocated. The extra byte is used to store a '\0', allowing the ->buf
+ * member to be a valid C-string. Every strbuf function ensure this
+ * invariant is preserved.
+ *
+ * Note that it is OK to "play" with the buffer directly if you work it
+ * that way:
+ *
+ * strbuf_grow(sb, SOME_SIZE);
+ * ... Here, the memory array starting at sb->buf, and of length
+ * ... strbuf_avail(sb) is all yours, and you are sure that
+ * ... strbuf_avail(sb) is at least SOME_SIZE.
+ * strbuf_setlen(sb, sb->len + SOME_OTHER_SIZE);
+ *
+ * Of course, SOME_OTHER_SIZE must be smaller or equal to strbuf_avail(sb).
+ *
+ * Doing so is safe, though if it has to be done in many places, adding the
+ * missing API to the strbuf module is the way to go.
+ *
+ * XXX: do _not_ assume that the area that is yours is of size ->alloc - 1
+ * even if it's true in the current implementation. Alloc is somehow a
+ * "private" member that should not be messed with.

- * Strbuf's can be use in many ways: as a byte array, or to store arbitrary
- * long, overflow safe strings.
- *
- * Strbufs has some invariants that are very important to keep in mind:
- *
- * 1. the ->buf member is always malloc-ed, hence strbuf's can be used to
- * build complex strings/buffers whose final size isn't easily known.
- *
- * It is NOT legal to copy the ->buf pointer away.
- * `strbuf_detach' is the operation that detachs a buffer from its shell
- * while keeping the shell valid wrt its invariants.
- *
- * 2. the ->buf member is a byte array that has at least ->len + 1 bytes
- * allocated. The extra byte is used to store a '\0', allowing the ->buf
- * member to be a valid C-string. Every strbuf function ensure this
- * invariant is preserved.
- *
- * Note that it is OK to "play" with the buffer directly if you work it
- * that way:
- *
- * strbuf_grow(sb, SOME_SIZE);
- * ... Here, the memory array starting at sb->buf, and of length
- * ... strbuf_avail(sb) is all yours, and you are sure that
- * ... strbuf_avail(sb) is at least SOME_SIZE.
- * strbuf_setlen(sb, sb->len + SOME_OTHER_SIZE);
- *
- * Of course, SOME_OTHER_SIZE must be smaller or equal to strbuf_avail(sb).
- *
- * Doing so is safe, though if it has to be done in many places, adding the
- * missing API to the strbuf module is the way to go.
- *
- * XXX: do _not_ assume that the area that is yours is of size ->alloc - 1
- * even if it's true in the current implementation. Alloc is somehow a
- * "private" member that should not be messed with.
