Map :bigint as NUMBER(19) sql_type by using `:limit => 19` for Oracle

Use --no-document option instead of --no-rdoc and --no-ri option

since NUMBER(8) is not enough to store the maximum number of bigint.
Oracle NUMBER(p,0) as handled as integer
because there is no dedicated integer sql data type exist in Oracle database.

Also NUMBER(p,s) precision can take up to 38. p means the number of digits, not the byte length.
bigint type needs 19 digits as follows.

	$ irb
	2.2.2 :001 > limit = 8
	 => 8
	2.2.2 :002 > maxvalue_of_bigint = 1 << ( limit * 8 - 1)
	 => 9223372036854775808
	2.2.2 :003 > puts maxvalue_of_bigint.to_s.length
	19
	 => nil
	2.2.2 :004 >

Update documentation for QueueAdapters::lookup [ci skip]

[ci skip] Used 'instance_variables' in example for consistency.

- Found that checking instance_variables elements using string object
  gives us 'false' value.
  `instance_variables.include? "@articles" # => false`
- Used only 'instance_variables' instead of using '.include?' on it. So
  that it will return recent instance variables list.

Passing 999999000 < `:nsec` < 999999999 and 999999 < `:usec` < 1000000
to change a time with utc_offset doesn't throw an `ArgumentError`.

Fixed typos [ci skip]

It's better to use Ruby methods when possible over methods defined by
Active Support because then it does not need to rely on any
dependencies.

The full command name is more expressive.

The version of SQLite used by Travis is outdated. We need to install a
newer version.

Our general contract in Active Record is that strings are assumed to be
SQL literals, and symbols are assumed to reference a column. If a from
clause is given, we shouldn't include the table name, but we should
still quote the value as if it were a column.

Upon fixing this, the tests were still failing on SQLite. This was
because the column name being returned by the query was `"\"join\""`
instead of `"join"`. This is actually a bug in SQLite that was fixed a
long time ago, but I was using the version of SQLite included by OS X
which has this bug. Since I'm guessing this will be a common case for
contributors, I also added an explicit check with a more helpful error
message.

Fixes #20360

The tests would still pass if the cache call in the rendered templates were removed.

Add tmp directory before touching

See #20299.

A lot of scripts assumes the existence of this folder and most would fail if it
is absent.

One example of this is `rake restart` (before the previous commit) – it tries to
`touch tmp/restart.txt`, which would fail if `tmp` does not exist, which was the
case for a freshly-cloned project as `tmp` is `.gitignored` by default.

See #20299.

[Yoong Kang Lim, Sunny Juneja]

In restart.rake, the creation of tmp/restart.txt
would fail if the tmp folder does not exist in the
app. This is a problem because apps cloned using
git would not have the tmp folder, as the folder is
in .gitignore. This commit creates the tmp folder
if it does not exist.

Fixes #20299
