The commit d04e72c9a5 introduced
the dynamic printf buffer allocation for each tplg_save_printf()
call.
Introduce 'struct tplg_buf' which carries extra information about
the temporary printf buffer and the destination buffer to save allocation
requests.
The printf buffer is also allocated using 1024 bytes chunks.
A comparison between 'alloc everyting' and 'cache+chunk alloc' for the
random picked topology file:
1: 18,620 allocs, 18,620 frees, 7,239,688 bytes allocated
2: 12,490 allocs, 12,490 frees, 962,568 bytes allocated

Some fields can exceed size limit, e.g. private data has no size
restriction. Therefore it needs to be dynamically increased.
