[Qemu-trivial] [PATCH v3 0/5] Trivial patch about qemu-char

[zhanghailiang]

Patch 1 and 2 fix check about parameter in chr_parse_* functions.
Patch 3 fix wrong english state in error message in windows part of the code.
The last two patches convert some open functions to use Error API.

In patch 4, i have tried to convert some codes which will be used 
in windows hypervisor. I didn't test them. But this is not too complex.

Markus has suggested add a separate patch for print_allowed_subtypes to use
error_prinf, but i think it's also in the context of "use Error API", so 
i fix it togther in patch 5.

v3:
- discard wrong modify about qemu_chr_open_pty (Michael Tokarev)
- use !str[0] in place of strlen(str) == 0 which makes more sense for parameter 
check (Michael Tokarev)
- Merge v2's patch 1 and 2 into a single patch (Michael Tokarev)
- Add new patch 3 to fix wrong english state in error message
- Use error_prinf instead of fprint for print_allowed_subtypes (Markus 
Armbruster) 

v2:
- don't use error_setg when followed by exit(), it does not report an error 
(Eric Blake)
- check the parameter in qemu_chr_parse_* functions and remove the check in 
qemu_chr_open_* functions. (Michael Tokarev)

Thanks very much for their reviews and suggestions;)
