0b063cb3c3 Change the default setting for --dsymutil from =no to =yes, since 
in practice it needs to be permanently enabled on OS X.  No change
on other platforms.

5582e3a511 Revisit r15601 (Change the --smc-check default value to =all-non-file.) 
to restrict the change to those architectures that do provide automatic
D-I coherence (x86, amd64, s390x).  This commit restores the default
value for all other architectures back to its pre r15601 state, so as not
to burden those architectures unnecessarily with =all-non-file.

Also, this rewrites the relevant manual section.

3a4ce80755 use verbosity 1 to report multiple termination of gdbserver, 
this can happen e.g.  in case of irrecoverable execve failure.

This log was making tests fail randomly: the double termination
can only occur if gdbsrv was initialised.
After fork, gdbsrv is initialised by the next scheduler gdbsrv
activity check (by default, every 5000 blocks).

As a double termination has no effect, switch the trace to level 1.

b00530b6de Distinguish properly when to establish the client data segment. 
Initial data segment is established (see initimg-solaris.c for rationale):
- directly during client program image initialization,
- or on demand when the executed program is the runtime linker itself,
  after it has loaded its target dynamic executable (see PRE(sys_mmapobj)),
  or when the first brk() syscall is made.

More preparatory work for ldsoexec support.

542fa886dc Initial data (brk) segment is setup on demand, when a first brk() syscall 
is made. It cannot be established during client image initialization because
that would conflict with a temporary stack which ld.so.1 (when executed directly)
uses for loading the target dynamic executable.
See PRE(sys_brk) in syswrap-solaris.c.

Preparatory work for ldsoexec support.

cdf7f871da Improve mmap MAP_HUGETLB support. 
This is a follow up to r14682:

When an mmap retry is done without any constraints, the kernel can
place it into free or reservation segments (i.e. anywhere there is no
mapping yet).
In r14682 a sanity check made the hypothesis that the new mapping was
in a free segment, but it does not hold at least on Linux 3.12 and 3.16
on amd64 (tested under Debian).
There is no risk in allowing the mapping to end up in (what was
previously) a reservation at this point, because it is also allowed.
