[Qemu-trivial] [PATCH v6 27/29] hw/xen*: Replace fprintf(stderr, "*\n" with error_report()

[Alistair Francis]

Replace a large number of the fprintf(stderr, "*\n" calls with
error_report(). The functions were renamed with these commands and then
compiler issues where manually fixed.

find ./* -type f -exec sed -i \
    'N;N;N;N;N;N;N;N;N;N;N;N; {s|fprintf(stderr, 
"\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \
    {} +
find ./* -type f -exec sed -i \
    'N;N;N;N;N;N;N;N;N;N;N; {s|fprintf(stderr, 
"\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \
    {} +
find ./* -type f -exec sed -i \
    'N;N;N;N;N;N;N;N;N; {s|fprintf(stderr, 
"\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \
    {} +

    'N;N;N;N;N;N;N;N; {s|fprintf(stderr,

    {} +

    'N;N;N;N;N;N;N; {s|fprintf(stderr,

    {} +
find ./* -type f -exec sed -i \
    'N;N;N;N;N;N; {s|fprintf(stderr,

    {} +
find ./* -type f -exec sed -i \

find ./* -type f -exec sed -i \
    'N;N;N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}'

    'N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \
    {} +

Some lines where then manually tweaked to pass checkpatch.

xen_pt_log() was left with an fprintf(stderr,

V3:
 - Don't change xen_pt_log()
V2:
 - Split hw patch into individual directories
