fosslinux a67db8fcbd Make patches relative to where tarballs are extracted 
Ever since an old patch version, it has (for reasonable security
reasons) not supported patched with ../ in the filename.
Many of our patches have been relying on this behaviour being OK,
because we start off with an ancient patch version that didn't perform
such checks. As soon as we need this behaviour after we build a newer
patch though, we will have problems.

So, let's change the policy.
Patches are relative to where tarballs are extracted, rather than the
"working directory" - e.g. have patches for `coreutils-9.4/src/cp.c`
instead of `src/cp.c`.
Keeping this consistent has a few implications;
- patches are applied from the build/ directory in bash era now, with
  `-p0`
- when patches are manually applied in the bash era, use `-p` as
  required, usually `-p1`
- in kaem era where patches are always manually applied, `-p1` is used

- * The ATM queuing discipline provides a framework for invoking classifiers
- * (aka "filters"), which in turn select classes of this queuing discipline.
- * Each class maps the flow(s) it is handling to a given VC. Multiple classes
- * may share the same VC.
- *
- * When creating a class, VCs are specified by passing the number of the open
- * socket descriptor by which the calling process references the VC. The kernel
- * keeps the VC open at least until all classes using it are removed.
- *
- * In this file, most functions are named atm_tc_* to avoid confusion with all
- * the atm_* in net/atm. This naming convention differs from what's used in the
- * rest of net/sched.
- *
- * Known bugs:
- * - sometimes messes up the IP stack
- * - any manipulations besides the few operations described in the README, are
- * untested and likely to crash the system
- * - should lock the flow while there is data in the queue (?)

- -----------------------------------------------------------------------
-
- Algorithm skeleton was taken from NS simulator cbq.cc.
- If someone wants to check this code against the LBL version,
- he should take into account that ONLY the skeleton was borrowed,
- the implementation is different. Particularly:
-
- --- The WRR algorithm is different. Our version looks more
- reasonable (I hope) and works when quanta are allowed to be
- less than MTU, which is always the case when real time classes
- have small rates. Note, that the statement of [3] is
- incomplete, delay may actually be estimated even if class
- per-round allotment is less than MTU. Namely, if per-round
- allotment is W*r_i, and r_1+...+r_k = r < 1
-
- delay_i <= ([MTU/(W*r_i)]*W*r + W*r + k*MTU)/B
-
- In the worst case we have IntServ estimate with D = W*r+k*MTU
- and C = MTU*r. The proof (if correct at all) is trivial.
-
-
- --- It seems that cbq-2.0 is not very accurate. At least, I cannot
- interpret some places, which look like wrong translations
- from NS. Anyone is advised to find these differences
- and explain to me, why I am wrong 8).
-
- --- Linux has no EOI event, so that we cannot estimate true class
- idle time. Workaround is to consider the next dequeue event
- as sign that previous packet is finished. This is wrong because of
- internal device queueing, but on a permanently loaded link it is true.
- Moreover, combined with clock integrator, this scheme looks
- very close to an ideal solution. */
