fix https://github.com/ruby/reline/issues/384
If `$TERM` is `vt102`, there are no `kend`, `khome`, `civis`, or `cnorm` in capabilities.
`TerminfoError` is raised in `Reline::Terminfo.tigetstr(capname)`, so it is rescued if it does not exist.

Since the default requirement in rubygems is ">= 0", it was failing to
match 0 prereleases. Changing the default globally to be ">= 0.a"
instead is a major refactoring that's quite tricky to make backwards
compatible, so I'm special casing this where needed for now to fix the
regression.

Instead of accessing the struct as an array, access it via methods. There are other places inside of this file already using this API (for example e0a5c3d2b7/lib/irb/ruby-lex.rb (L829-L830)).
This commit moves all struct array-ish calls to use their method calls instead. It is also ~1.23 faster accessing values via a method instead of as an array according to this microbenchmark:
```ruby
Elem = Struct.new(:pos, :event, :tok, :state, :message) do
def initialize(pos, event, tok, state, message = nil)
super(pos, event, tok, State.new(state), message)
end
# ...
def to_a
a = super
a.pop unless a.empty?
a
end
end
class ElemClass
attr_accessor :pos, :event, :tok, :state, :message
def initialize(pos, event, tok, state, message = nil)
@pos = pos
@event = event
@tok = tok
@state = State.new(state)
@message = message
end
def to_a
if @message
[@pos, @event, @tok, @state, @message]
else
[@pos, @event, @tok, @state]
end
end
end
# stub state class creation for now
class State; def initialize(val); end; end
```
```ruby
Benchmark.ips do |x|
x.report("struct") { struct[1] }
x.report("class ") { from_class.event }
x.compare!
end; nil
```
```

It seems that since ruby openssl 2.1.0 [[1]], the distinguished name
submitted to `OpenSSL::X509::Name.parse` is not correctly parsed if it
does not contain the first slash:
~~~
$ ruby -v
ruby 3.0.2p107 (2021-07-07 revision 0db68f0233) [x86_64-linux]
$ gem list | grep openssl
openssl (default: 2.2.0)
$ irb -r openssl
irb(main):001:0> OpenSSL::X509::Name.parse("CN=nobody/DC=example").to_s(OpenSSL::X509::Name::ONELINE)
=> "CN = nobody/DC=example"
irb(main):002:0> OpenSSL::X509::Name.parse("/CN=nobody/DC=example").to_s(OpenSSL::X509::Name::ONELINE)
=> "CN = nobody, DC = example"
~~~
Instead, use `OpenSSL::X509::Name.new` directly as suggested by upstream
maintainer.

This change avoids a YAML Float-to-String conversion, which turns a 3.0 into a "3". That can make names of builds less clear.
In order to use this new capability, I added a "name" descriptor to the matrix-created Job.

When bundler parallel installer installs gems concurrently, one can get
confusing warnings like the following:
```
"[/home/runner/work/rubygems/rubygems/bundler/tmp/2/gems/system/specifications/zeitwerk-2.4.2.gemspec] isn't a Gem::Specification (NilClass instead).
```
I've got these warnings several times in the past, but I never managed
to reproduce them, and never look deeply into the root cause, but this
time a got a cause that reproduced quite frequently, so I looked into
it.
The problem is one thread reading a gemspec while another thread is
writing it. The write of the gemspec was not protected, so
`Gem::Specification.load` could end up seeing a truncated gemspec and
thus throw this warning.
The fix involve two changes:
* Change the methods that write gemspecs to use `Gem.binary_write` which
is protected by a lock.
* Fix `Gem.binary_write` to create the file lock at file creation time,
not when the file already exists after.
The realworld user problem caused by this issue happens in bundler, but
I'm fixing it in rubygems first, and then I'll backport to bundler
whatever needs backporting to fix the issue on the bundler side.

This reverts commit af604436d8141c34cb2e1e645b9b0d47bfd55a55.
The issue that led to introducing it was never reproduced. I tried to
repro with this patch and it still works just fine. Since this removal
is getting in the middle for some race conditions I'm facing, I'm
reverting the patch.

fix https://github.com/ruby/irb/issues/308
This bug occurred when `dialog.width - calculate_width(s, true)` was negative.
When `dialog.width` is shorter than `old_dialog.width`, it calculates how much padding it has to do. However, there are cases where `s` is longer than `dialog.width`, as in the issue. In that case, `padding_space_with_escape_sequences` will crash.
Here, `old_dialog.width` is longer than `dialog.width`, so I changed the padding width to `old_dialog.width - dialog.width`.
