884d3ae479 Remove RVAL_PRINT_ERR_VAL
* defs.h (RVAL_PRINT_ERR_VAL): Remove.
* ldt.c (SYS_FUNC(modify_ldt)): Return 0.
* syscall.c (syscall_exiting_trace): When printing an error,
always print struct tcb.u_rval as if RVAL_PRINT_ERR_VAL was set.

0c7e458044 Allow separate printing of struct user_desc.entry_number
Kernel reads only entry_number field in the beginning of the
get_thread_area syscall handler.  Let's replicate this behaviour.

* defs.h (enum user_desc_print_filter): New enumeration.
(print_user_desc): Add an argument for signalling which part of the
structure should be printed.
* clone.c (print_tls_arg): Update print_user_desc call.
* ldt.c (print_user_desc): Add filter argument.  Print entry_number on
entering and the rest on exiting. Store entering value of the
entry_number field in order to print the updated value in the impossible
case of changed entry_number value.
(SYS_FUNC(modify_ldt), SYS_FUNC(set_thread_area)): Update
print_user_desc call.
(SYS_FUNC(get_thread_area)): Call print_user_desc with
USER_DESC_ENTERING format argument on entering and with
USER_DESC_EXITING on exiting.

8830aa8fca ldt.c: manually set modify_ldt's error code
* ldt.c (modify_ldt): Move parsing under entering(tcp). Check whether
return code is erroneous and set tcp->u_error appropriately along with
RVAL_PRINT_ERR_VAL flag.

916cb4ec13 ldt.c: print lm field for 64-bit tracees

* ldt.c (print_user_desc) [HAVE_STRUCT_USER_DESC_LM]: Print lm field
for non-compat tracees (it is ignored for compat ones).

3d51a91276 ldt.c: make struct user_desc output more structured
Also, while we are here, let's fix print qualifiers (which should be %u
and not %d).

* ldt.c (print_user_desc): Use PRINT_FIELD_* macros for printing
structure.
(SYS_FUNC(set_thread_area)): Change field key-value separator from ":"
to "=", change print format qualifier from %d to %u.

38a34c9349 Add copyright headers to some files which lack them
Before this change, all files that exist since 20th century had
copyright headers, while most files that appeared later didn't.  This
change fixes the inconsistency by adding missing copyright headers.

It doesn't mean that copyright headers became maintained.  In my view,
git history provides much better information on this subject and is much
more accurate than copyright headers.
