Inside parentheses, line-initial commas align with the open parenthesis

For example:

  [ one
  , two
  , three
  ]

This does not affect coding styles that don't put commas at the
beginning of lines.

Fix httpd config option 'erl_script_nocache'

This fixes the usage of the httpd configuration option
'erl_script_nocache', which got ignored before.

Attention: Before, the option 'script_nocache' also changed the
behavior for mod_esi, now it only affects mod_cgi.
Added a few input checks which prevent odbcserver crash if it's executed
and supplied incorrect data to stdin. A crash example:

echo -en "\x0\x0\x0\x1\x0" | ./odbcserver
Allow calls to ct:pal and ct:print even if CT is not running

Also make sure calls to ct:log and ct:pal don't cause crash
if test_server is not running (could happen during startup or
shutdown of CT).

Minor correction of xml structure to conform to the DTD
Add application:ensure_all_started/1-2

This adds two new functions to the application module that will
recursively look for missing dependencies to start the entire dependency
chain of a given application, and then the application itself, if
possible.

Its entire behavior is based on the currently existing 'start/1-2'
functions, which will report dependencies that have not yet been started
and other problems encountered. 'ensure_all_started/1-2' will use this
information the way any programmer would manually do it to automate the
process.

This kind of functionality, while not OTP-ish (releases do this start
sequence for the user), is still useful for testing purposes, quick
demonstrations, and programmers who do not wish or know how to use OTP
releases.

The function returns '{ok, StartedApps}' for all started or already
started applications (already started are omitted from the list), and
will return '{error, {AppName, Reason}}' on a failure to allow users to
rapidly know why the function failed.

Note that no specific check is made for direct or indirect circular
dependencies between applications, and these will make the function go
in an infinite loop.
Add Fd usage in rb logging

rb was only accepting physical filenames as log file.
This patch allow rb to accept now any io_device, valid registered name,
except standard_error which is replaced by standard_io.
Creation of two new exported functions : rb:log_list/0-1
that print in log file if existing, otherwise on standard_io.
Add new functions documentation and tests in rb_SUITE.

Fix compile error on ARM and GCC < 4.1.0

Since b29ecbd (OTP-10418, R15B03) Erlang does not compile anymore with
old versions of GCC that do not have atomic ops builtins on platforms
where there is no native ethread implementation (e.g. ARM):

In file included from ../include/internal/gcc/ethread.h:29,
                 from ../include/internal/ethread.h:354,
                 from beam/erl_threads.h:264,
                 from beam/erl_smp.h:27,
                 from beam/sys.h:413,
                 from hipe/hipe_mkliterals.c:29:
../include/internal/gcc/ethr_membar.h:49:4: error: #error "No __sync_val_compare_and_swap"

This patch adds a header guard in "gcc/ethread.h", as is present in
"libatomic_ops/ethread.h".
Document socket option 'netns'
erts: Extend erl_driver interface with lock names

Lock and thread names are already a feature in the driver interface.
This extension will let developers read these names. Eases debugging.
Bailout if no native implementations are found

Some basic tests are already done in configure. This makes sure we
cover all cases by bailing out when compiling as well.
