libsndfile1: update security patches

Remove CVE-2017-14245-14246.patch, fix rejected upstream as it doesn't solve the
underlying issue.

Instead 0001-a-ulaw-fix-multiple-buffer-overflows-432 also solves CVE-2017-14245
and CVE-2017-14246 properly.

Add patches for CVE-2017-12562 and CVE-2018-19758.

Refresh CVE-2018-13139.patch.

+Subject: [PATCH] src/common.c: Fix heap buffer overflows when writing strings
+ in binheader
+
+Fixes the following problems:
+ 1. Case 's' only enlarges the buffer by 16 bytes instead of size bytes.
+ 2. psf_binheader_writef() enlarges the header buffer (if needed) prior to the
+    big switch statement by an amount (16 bytes) which is enough for all cases
+    where only a single value gets added. Cases 's', 'S', 'p' however
+    additionally write an arbitrary length block of data and again enlarge the
+    buffer to the required amount. However, the required space calculation does
+    not take into account the size of the length field which gets output before
+    the data.
+ 3. Buffer size requirement calculation in case 'S' does not account for the
+    padding byte ("size += (size & 1) ;" happens after the calculation which
+    uses "size").
+ 4. Case 'S' can overrun the header buffer by 1 byte when no padding is
+    involved
+    ("memcpy (&(psf->header.ptr [psf->header.indx]), strptr, size + 1) ;" while
+    the buffer is only guaranteed to have "size" space available).
+ 5. "psf->header.ptr [psf->header.indx] = 0 ;" in case 'S' always writes 1 byte
+    beyond the space which is guaranteed to be allocated in the header buffer.
+ 6. Case 's' can overrun the provided source string by 1 byte if padding is
+    involved ("memcpy (&(psf->header.ptr [psf->header.indx]), strptr, size) ;"
+    where "size" is "strlen (strptr) + 1" (which includes the 0 terminator,
+    plus optionally another 1 which is padding and not guaranteed to be
+    readable via the source string pointer).
