[PATCH v2 0/5] gdb: introduce limited array lengths while printing values

["Maciej W. Rozycki" <macro@embecosm.com>]

Hi,

 This is v2 of Andrew's RFC, originally posted here: 
<https://sourceware.org/pipermail/gdb-patches/2021-October/182435.html>.

 Following Tom's feedback I have updated the original change so that data 
up to `max-value-size' is retrieved and stored in the history regardless 
of how much less has been requested with the relevant `print' command.  

 This has revealed issues with value history handling where entries were 
not retrieved due to `max-value-size' setting where accessing the original 
data object would work, and then where out of range accesses pretended to 
retrieve data or returned memory faults.

 I have updated the change to make the `output' command follow the same 
rules (except for storing the value retrieved in the value history of 
course).  This in turn required a test framework update as it seems the 
only command that does not produce a new line character/sequence between 
data output and the following command prompt; this has also revealed this 
command had no testsuite coverage at all until now.

 Consequently this has now become a patch series addressing each of these 
issues individually.  See individual change descriptions (and any extra 
discussion) for details.

 I have regression-tested it natively with a `x86_64-linux-gnu' system.  
OK to apply?
