Subject: [PATCH 3/3] delay: add generic udelay(), mdelay() and ssleep()

This patch does the following:
* make it so than asm/delay.h does not define udelay(),
  only __udelay(), to be used in generic udelay()
* add generic udelay() which calls __udelay() repeatedly
  as needed. Protect against overflow in udelay() argument.
* similarly for mdelay() and ssleep()
* __const_udelay for all arches is removed or renamed to
  __const_delay (it did not do microsecond delays anyway)
  if still used by arch ndelay() function/macro
* remove EXPORT_SYMBOL(__udelay). It is not used in modules
  anymore
* remove MAX_UDELAY_MS

We specifically do not touch ndelay() in these patches.
