* util/cutils: Change qemu_strtosz*() from int64_t to uint64_tMarkus Armbruster2017-02-231-3/+3

* util/cutils: Return qemu_strtosz*() error and value separatelyMarkus Armbruster2017-02-231-3/+3
| | | | | | | | | | | | | | | | This makes qemu_strtosz(), qemu_strtosz_mebi() and qemu_strtosz_metric() similar to qemu_strtoi64(), except negative values are rejected.

* util/cutils: New qemu_strtosz()Markus Armbruster2017-02-231-16/+1Star
| | | | | | | | | | | Most callers of qemu_strtosz_suffix() pass QEMU_STRTOSZ_DEFSUFFIX_B. Capture the pattern in new qemu_strtosz(). Inline qemu_strtosz_suffix() into its only remaining caller.

* util/cutils: Rename qemu_strtosz() to qemu_strtosz_MiB()Markus Armbruster2017-02-231-1/+1
| | | | | | | | | | | With qemu_strtosz(), no suffix means mebibytes. It's used rarely. I'm going to add a similar function where no suffix means bytes. Rename qemu_strtosz() to qemu_strtosz_MiB() to make the name qemu_strtosz() available for the new function.

* util/cutils: New qemu_strtosz_metric()Markus Armbruster2017-02-231-2/+2
| | | | | | | | | | | | | | | | | | | To parse numbers with metric suffixes, we use qemu_strtosz_suffix_unit(nptr, &eptr, QEMU_STRTOSZ_DEFSUFFIX_B, 1000) Capture this in a new function for legibility: qemu_strtosz_metric(nptr, &eptr) Replace test_qemu_strtosz_suffix_unit() by test_qemu_strtosz_metric(). Rename qemu_strtosz_suffix_unit() to do_strtosz() and give it internal linkage.

* util/cutils: Rename qemu_strtoll(), qemu_strtoull()Markus Armbruster2017-02-231-3/+3
| | | | | | | | | | | | | The name qemu_strtoll() suggests conversion to long long, but it actually converts to int64_t. Rename to qemu_strtoi64(). The name qemu_strtoull() suggests conversion to unsigned long long, but it actually converts to uint64_t. Rename to qemu_strtou64().

| | | | | | | | | | | | Since the two users don't make use of the returned offset, beyond ensuring that the entire buffer is zero, consider the can_use_buffer_find_nonzero_offset and buffer_find_nonzero_offset functions internal.

Move declarations out of qemu-common.h for functions declared in utils/ files: e.g. include/qemu/path.h for utils/path.c.
