Subject: common: move copy_filter_bytecode to bytecode.c and rename it
X-Git-Tag: v2.13.0-rc1~264
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=763f0d4cef1438d3f1f5f5c5a232d72628bca550;p=lttng-tools.git

common: move copy_filter_bytecode to bytecode.c and rename it

Since there's now a file dedicated to bytecode stuff, that is
independent of filters, move copy_filter_bytecode there.  Rename it to
`bytecode_copy`.
