Paolo Bonzini 8fbe3d1fcf CODING_STYLE, checkpatch: update line length rules
Line lengths above 80 characters do exist.  They are rare, but
they happen from time to time.  An ignored rule is worse than an
exception to the rule, so do the latter.

Some on the list expressed their preference for a soft limit that
is slightly lower than 80 characters, to account for extra characters
in unified diffs (including three-way diffs) and for email quoting.
However, there was no consensus on this so keep the 80-character
soft limit and add a hard limit at 90.

Paolo Bonzini 690a35e1f2 CODING_STYLE: update mixed declaration rules
Mixed declarations do come in handy at the top of #ifdef blocks.
Reluctantly allow this particular usage and suggest an alternative.

Gonglei 2bb0020cf9 CODING_STYLE: Section about conditional statement
Yoda conditions lack readability, and QEMU has a
strict compiler configuration for checking a common
mistake like "if (dev = NULL)". Make it a written rule.

We had an unwritten rule about declarations having to be at beginning of

Avi Kivity 5f070c5fb7 CODING_STYLE: explicitly allow braceless 'else if'
It's already allowed by the example; there are about 1800 instances in the
tree; and disallowing it would lead to

    if (a) {
        ...
    } else {
        if (b) {
            ...
        } else {
            if (c) {
                ...
            } else {
                if (d) {
                    ...
                } else {
                    ...
                }
            }
        }
    }

instead of

    if (a) {
        ...
    } else if (b) {
        ...
    } else if (c) {
        ...
    } else if (d) {
        ...
    } else {
        ...
    }

which is more readable.

Anthony Liguori c227f0995e Revert "Get rid of _t suffix"
In the very least, a change like this requires discussion on the list.

The naming convention is goofy and it causes a massive merge problem.  Something
like this _must_ be presented on the list first so people can provide input
and cope with it.

This reverts commit 99a0949b72.
