There are some regex expressions in the kernel-doc script, which are used
repeatedly in the script.

Reduce such expressions into variables, which can be used everywhere.

A quick manual check found that no errors and warnings were added/removed
in this process.

Changes in v3:
- Remove variables for separate qualifiers in "sub dump_struct"
- Make a common variable for all the qualifiers
- Make $attribute global variable to use it at "sub check_sections" as well

Changes in v2:
- Rename $pointer_function to $function_pointer
- Combine elsif-block expressions at "sub dump_function" into lesser regex expressions
- Combine $prototype_end1,$prototype_end2 expressions into a common $prototype_end

So this looks good but ... it adds a warning to the build:

/stuff/k/git/kernel/Documentation/driver-api/media/v4l2-controls:823: ./include/media/v4l2-ctrls.h:964: WARNING: Invalid C declaration: Expected identifier in nested name. [error at 6]
  const * v4l2_ctrl_get_menu (u32 id)
  ------^

So it looks like something isn't being parsed quite identically?

Hi Jonathan!
I could not reproduce this error..
Can you suggest me how can I reproduce this error?
I ran kernel-doc -none {$file} over the tree.

Probably, this is not a kernel-doc error

Thanks
Aditya
