f47a931b8c Linux system call wrappers: truncate ioctl request number to 32 bits 
As explained in https://bugs.kde.org/show_bug.cgi?id=331829, when passing
an ioctl request number as an int to a function the request number will
be sign-extended to 64 bits on 64-bit systems. Avoid that this causes
Valgrind to fail to recognize an ioctl by truncating the request number
to 32 bits.

eb2b193943 Fix dangling ref in m_errormgr.c + report all uninit fields in a syscall param 
Some syscall verification code is allocating memory to generate 
the string used to build an error, e.g. syswrap-generic.c verifying fields of
e.g socket addresses (pre_mem_read_sockaddr) or sendmsg/recvmsg args 
(msghdr_foreachfield)

The allocated pointer was copied in the error created by VG_(maybe_record_error).

This was wrong for 2 reasons:
1. If the error is a new error, it is stored in a list of errors,
   but the string memory was freed by pre_mem_read_sockaddr, msghdr_foreachfield, ...
   This causes a dangling reference. Was at least visible when giving -v, which
   re-prints all errors at the end of execution.
   Probably this could have some consequences during run while generating new errors,
   and comparing for equality with a recorded error having a dangling reference.
2. the same allocated string is re-used for each piece/field of the verified struct.
   The code in mc_errors.c that checks that 2 errors are identical was then wrongly
   considereing that 2 successive errors for 2 different fields for the same syscall
   arg are identical, just because the error string happened to be produced at
   the same address.
(it is believed that initially, the error string was assumed to be a static
string, which is not the case anymore, causing the above 2 problems).

Changes:
* The fix consists in duplicating in m_errormgr.c the given error string when
  the error is recorded. In other words, the error string is now duplicated similarly
  to the (optional) extra component of the error.

* memcheck/tests/linux/rfcomm.c test modified as now an error is reported
  for each uninit field.

* socketaddr unknown family is also better reported (using sa_data field name,
  rather than an empty field name.

* minor reformatting in m_errormgr.c, to be below 80 characters.

Some notes:
1. the string is only duplicated if the error is recorded
   (ie. printed or the first time an error matches a suppression).
   The string is not duplicated for duplicated errors or following errors
   matching the first (suppressed) error.
   The string is also not duplicated for 'unique errors' (that are printed
   and then not recorded).
2. duplicating the string for each recorded error is not deemed to
   use a lot of memory:
     * error strings are usually NULL or short (often 10 bytes or so).
     * we expect no program has a huge number of errors
   If ever this string duplicate would be significant, having a DedupPoolAlloc
   in m_errormgr.c for these strings would reduce this memory (as we expect to
   have very few different strings, even with millions of errors).
