Add x-IBM-1129 charset

[Nasser Ebrahim]

Hello,

I just realized that I missed to provide the details of the test I have 
conducted for the new charset IBM-1129. Please note that I have done the 
following jtreg tests to make sure the new charset is working properly.

sun.nio.cs.TestCharsetMapping
java.nio.charset.Charset.RegisteredCharsets
sun.nio.cs.CheckHistoricalNamesTest
java.nio.charset.RemovingSunIO.SunioAlias

Please let me know if I have to run any additional tests.

Am aware of the suggestion from Alan and Thomas in the mail thread 
http://mail.openjdk.java.net/pipermail/core-libs-dev/2018-May/053316.html 
to move the IBM platform specific charsets to a separate module instead of 
adding to jdk.charsets.  We will open another thread to discuss that topic 
as we would like to contribute many more extended charsets. However, I 
believe we can still consider integrating this charset without waiting for 
the conclusion of that discussion as this charset is part of default 
charset for AIX and needs to be part of the java.base. If we decided to 
move the IBM charsets out of jdk.charsets, we can move this charsets as 
well for non-AIX platforms.

Kindly request you to open a bug/RFE for this change request, review the 
fix and provide your feedback.

Thank you,
Nasser Ebrahim

Hello,
 
With the following three bugs, all the default locale charsets except two 
(Vi_VN.IBM-1129 & ja_JP.IBM-eucJP) are fixed for AIX platform.
 
- JDK-8201540: [AIX] Extend the set of supported charsets in java.base
- JDK-8202329: Codepage mappings for IBM-943 and Big5 (aix)
- 
http://mail.openjdk.java.net/pipermail/core-libs-dev/2018-May/053050.html 
: [AIX] Add charset IBM-964 (default charset for zh_TW.IBM-eucTW) to stdcs 
[bug not yet opened].
 
For those fixed charsets, the charsets were existing in the extended 
charsets (jdk.charsets) and they were not working with default locale 
charset as it did not exist in the standard charset (java.base). The 
charsets correspond to the two pending locale (Vi_VN.IBM-1129 & 
ja_JP.IBM-eucJP) does not exist in the jdk. They need to be added to the 
extended charsets before adding to stdcs on AIX platform.
 
Here, am including the patch to fix  the charset IBM-1129 for the locale 
Vi_VN.IBM-1129. We are working on the other missing charset (for 
ja_JP.IBM-eucJP) which will be contributed in some time.
 
The webrev of the fix is available at 
http://cr.openjdk.java.net/~aleonard/IBM1129/webrev.00/
 
Kindly request you to open a bug and review the fix. Please let me know if 
you have any questions.
 
Thank you,
